When he enters the White House, Donald Trump is going to need a resolution of the Ukraine conflict. But Russia’s decision-makers are unlikely to yield to him. Even if Trump got his way, the underlying issues between Russia and the West would persist.

As the world looks back into a turbulent 2024, the Nobel Peace Prize awarded to Hiroshima and Nagasaki survivors underscores the urgent need for renewed global efforts to mitigate nuclear risks. In the face of rising geopolitical tensions and technological advancements, we must revive strategic dialogues and prioritize diplomatic solutions, following President Kennedy’s example, to ensure global security and address the existential threats posed by nuclear weapons and AI-enhanced warfare. And this call demands leadership.

Recent developments signal a potential thaw in U.S.-China space cooperation, as NASA’s outreach sparks cautious optimism but also draws sharp political criticism from China, highlighting both the promise and the challenges of collaboration amidst broader tensions.

While Tsai’s stance may momentarily shift Trump’s administration's attention in East Asia, it risks undermining his likely focus on ending the costly Ukraine conflict and confronting China more aggressively, with Taiwan as a key flashpoint.

Threats of violence are pushing the region to the brink. Israel said it would exact a “deadly and heavy” toll for any Iranian attack.
