This article is a contribution to the ongoing debate regarding the changing dynamics of global power relations, which seem to be heading toward an inevitable end of the unipolar world order dominated by the United States since the collapse of the Soviet Union in 1990. It demonstrates that through highlighting the rising global power of China and Russia, which is currently causing a substantial threat to the US hegemony. As such, the continuation of this trajectory in the upcoming decades will likely lead to the emergence of a tri-polar world order, whereby the international system will be shared among the US, China and Russia. Methodologically, this article primarily relies on content analysis and thorough scrutinization of recent official foreign policy and national security documents issued by these actors in order to provide an in-depth understanding of the respective strategic vision underpinning.

The success and widespread deployment of artificial intelligence (AI) have raised awareness of the technology's economic, social, and political consequences. Each new step in the development and application of AI is accompanied by speculations about a supposedly imminent but largely fictional artificial general intelligence (AGI) with (super-)human capacities, as seen in the unfolding discourse about capabilities and impact of large language models (LLMs) in the wake of ChatGPT. These far- reaching expectations lead to a discussion on the societal and political impact of AI that is largely dominated by unfocused fears and enthusiasms. In contrast, this article provides a framework for a more focused and productive analysis and discussion of AI's likely impact on one specific social field: democracy. First, it is necessary to be clear about the workings of AI. This means differentiating between what is at present a largely imaginary AGI and narrow artificial intelligence focused on solving specific tasks. This distinction allows for a critical discussion of how AI affects different aspects of democracy, including its effects on the conditions of self-rule and people's opportunities to exercise it, equality, the institution of elections, and competition between democratic and autocratic systems of government. This article shows that the consequences of today's AI are more specific for democracy than broad speculation about AGI capabilities implies. Focusing on these specific aspects will account for actual threats and opportunities and thus allow for better monitoring of AI's impact on democracy in an interdisciplinary effort by computer and social scientists.

The notions of superpower and unipolarity are seriously questioned by heavy trends: non-fungibility and dissemination of power; complexity of transnational interactions and interdependencies. The article argues that because of these mutations, China's rise, achieving the rank of "emerging potential superpower", and the narrowing of the gape on global power resources, the United State, who still have unmatched capacity, will probably be the last superpower in a Cold war era sense. The article concludes that unipolarity is not challenged because the operating interstate dynamics, in which involved actors which are supposed to work for building a multipolar world, contribute in fact to reproducing unipolarity.

The contemporary Yemeni state is characterized by strife and complications involving all aspects of the state and society. These complexities go back to the era of its inception and continue today, leaving serious implications for the political, geographic and social unity of Yemen. There are very clear intersections between the internal (political, economic, social) and external components, which contribute to the sustained crisis in the Yemeni state. Successive Yemeni governments have failed to fulfill their assumed duties and functions, thus preventing them from dealing with all kinds of foreign interventions. Moreover, tribal and sectarian roles in Yemen have historically prevailed over other Yemeni political roles, which have not succeeded in transferring Yemen to civil rule. Nor have they managed to build a democratic model that achieves stability and allows Yemenis to participate actively in the political and economic process, consolidate the concepts of citizenship and the rule of law, and safeguard the various rights and freedoms of all members of Yemeni society.

This study examines US foreign policy and the changes that occurred under former President Donald Trump, compared to other post-Cold War administrations, assessing their impact on the future of US hegemony and the liberal international system, with projections for current president Joe Biden's rule. Two main questions arise: First, what foreign policies did Trump pursue? Second, what impact do they have on the future of US hegemony and the liberal international order? The analysis studies the concept of hegemony in international relations theory. It concludes with three possible scenarios awaiting the future of US hegemony under Biden's rule, with his administration likely to move between partial reform and catastrophic failure.

After the collapse of the Soviet Union, neorealist theory came under severe scrutiny. During its growth stages, the theory encountered unavoidable conceptual and empirical impediments, which cast doubt on its capacity to overcome such hurdles. This was the challenge that neorealist theory faced when the concepts of "anarchy" and "balance" were questioned. In terms of empiricism, the criticism focused on the neorealism inability to represent the new realities of the international system, notably US hegemony. This study evaluates the progressiveness or degenerassive of the neorealism research program in an attempt to assess the theory's progressivism and degenerative by examining the adjustments and improvements made to the ideas of anarchy and balance. It is based on the methodology of the Imre Lakatos Scientific Research Program as an evaluation tool.

The book focused on the study of the US case, examining the approaches of the force on which it relied to control the course of change in the international system, and analyzing it for its own strengths.

​If deterrence fails and diplomacy falters, how can small states defend themselves against adversaries that outnumber, outgun and outmatch them? This study seeks to contribute to the ongoing scholarly discourse on how "the few" can achieve a military upset - not just a political or a propaganda one- against "the many." In an era where asymmetric war has become the most anticipated type, understanding the innovative ways of warfare that enable the smaller forces to endure and even prevail is of paramount importance to strategic analysts, military commanders, and policymakers alike. To do so, the study coins a definition for the concept of "Hybrid Defence," contributes a new definition of "Multi-Domain Combined Arms Operations" and examines their correlations with, and impacts on, "Military Effectiveness" and "Combat Effectiveness." It then analyses selected operational arts and tactical adaptations employed by the relatively smaller forces - such as the Ukrainian Military and Security Forces, as well as nonstate forces, exemplified by the Palestinian Resistance Factions in Gaza - for confronting numerically and technologically superior adversaries. The study extracts seven key lessons and concludes with their comparative implications for the defence policies of small states, particularly in the Arab world and beyond.

This article traces the different paths taken by constructivism in International Relations, from its emergence as a critical social theory in the 1980 s, in response to the third debate between positivist rationalists and post-positivist reflectivists, to Alexander Wendt's project to seize a middle ground and to bridge the rationalist–reflectivist epistemological gap. The article, then, examines the intra-debates among conventional and critical constructivists on Went's project, as well as the rise of the new constructivism after Wendt left the constructivist research program. The article explores the Wendtian project's epistemological tensions and demonstrates how such tensions led to a plurality within constructivism: modernist conventional and postmodernist critical (reflectivist). It highlights that Wendt's leaving constructivism and his shift to a quantum approach have not caused constructivism to decline, but instead, it continued to thrive through the efforts of a new generation of constructivists. The article argues that three main developments in International Relations over the past twenty years have contributed to its ongoing thriving: the decline of epistemological polarization among IR theories; the rise of critical realism as a philosophy of science in International Relations, and the emergence of analytical eclecticism.

This study investigates the circumstances under which military governments leave power. It shows that there is no single path to get the military out of power, as there are no general rules for all cases. Nevertheless, several lessons are learned of which the most important is that military officers never relinquish power on their own. Rather, they are usually forced to leave it. In most cases, forcing the military to hand over authority requires a democratic opposition bloc that reaches a national consensus and agrees on a clear political strategy with an explicit goal. This will get the military out of power and establish a civilian government. A consensus or democratic bloc enables reformist democrats to change the balance of power for the benefit of democratic transition.
