America's dangerous friends America's enemies are becoming more dangerous, but even its friends could drag it into expanded conflicts this year. Volodymyr Zelensky. President Joe Biden has been Ukraine's staunchest supporter since Russia's invasion in February 2022. Having pledged to stay by Kyiv's side "as long as it takes," he has shepherded $113 billion in military and other aid that has proven vital to Ukrainians' ability to defend themselves. Biden has done this even though he neither likes nor trusts President Zelensky. However, political support for Ukraine within the US has wavered as the war has dragged on, seriously undermining Biden's ability to keep the aid coming past this year. And if Donald Trump-who considers Zelensky a personal adversary-wins in November, Ukrainians can wave goodbye to their biggest backer (please see Top Risk #1). Cracks have also emerged within Ukraine, where infighting between Zelensky and Chief of the Armed Forces Valery Zaluzhny (over military strategy) as well as Kyiv Mayor Vitali Klitschko (over Zelensky's allegedly authoritarian leadership) has spilled into the open, threatening Ukrainian political unity and fueling more skepticism among Kyiv's friends. Under pressure domestically and frustrated with both diminishing US support and increasing difficulties on the battlefield, a desperate Zelensky will be willing to take bigger risks to turn the war around and maintain his political standing before Trump potentially takes office (please see Top Risk #3). This includes more aggressive attacks against targets in Russia, Crimea, and the Black Sea, threatening a response from Russia and potentially forcing the United States to become more directly involved in the war. Benjamin Netanyahu. Israel is America's closest ally in the Middle East, the only democracy in the region, and the largest cumulative recipient of US foreign aid. It is no surprise that Biden-a self-described Zionist and longtime Israel supporter-strongly backed Israel's initial response to Hamas's 7 October attacks, despite his complicated relationship with Prime Minister Benjamin Netanyahu. Since then, however, a public rift has opened between the two over the conduct and endgame of the war in Gaza. They are also at odds about the role the Palestinian Authority should play in Gaza's postwar governance as well as the viability of a two-state solution. Fundamentally, Biden wants to see the war end, while Netanyahu has political and personal reasons to keep it going or even escalate it. eurasia group TOP RISKS 2024 Determined to stay in power and out of jail and emboldened by the possibility that his friend Trump returns to power in January 2025, Netanyahu will push back against pressure from Biden to end the war. He will ignore calls for restraint in Gaza while eyeing more conflict with Hezbollah in the north (please see Top Risk #2). He will also continue to inflame tensions in the West Bank and thwart any efforts to create a Palestinian state in the future. As a result, the United States will be inextricably tied to an intensifying conflict over which it has limited influence-one that will further strain US relations with the Arab world, the Global South, and even some allies, as well as create political challenges for Biden at home. Should Netanyahu decide to preemptively strike Hezbollah or even Iran itself, the US would find itself drawn into a much broader Middle East war. William Lai. Washington's long-standing "one China" policy and its security cooperation with Taiwan have been critical to deterring both a Chinese invasion and a declaration of independence from Taipei. Although Biden has repeatedly said the US would defend Taiwan against a Chinese attack, "strategic ambiguity" remains the official stance, and the president has no desire to risk a crisis with Beijing over the island. But the uneasy status quo in the Taiwan Strait will soon be tested if Taiwan elects Vice President William Lai, the ruling party candidate whom China views as the most pro independence Taiwanese leader in a generation, as president (and his running mate Hsiao Bi-khim, Taiwan's former representative to the US, as vice president). While Biden will oppose any de jure independence moves from Lai, the domestic politics of the Taiwan issue will prevent the US president from objecting to the smaller, symbolic steps toward de facto autonomy Lai is likely to take. Yet even these will be enough to provoke a beyond-precedent military response from Beijing, such as violating Taiwan's airspace or waters or conducting ship inspections. Biden will be forced to respond to Chinese aggression with a show of resolve in support for Taipei that could jeopardize the US-China thaw and risk a dangerous cycle of escalation. Ukraine, Israel, and Taiwan will all continue to be major US allies. But their leaders' pursuit of their national-and, occasionally, personal-interests will further entangle Washington in growing conflicts. 20
