What is Donald Trump's approach to reducing global defense spending and what challenges does this proposal face?

Donald Trump proposes to significantly reduce global defense spending through direct diplomatic engagement, planning meetings with Russia's Vladimir Putin and China's Xi Jinping to discuss cuts. His approach advocates for denuclearization and redirecting the substantial military budgets—including the U.S.'s projected $850 billion for fiscal year 2025, China's $541 billion, and Russia's dramatically increased spending—toward other priorities. However, this proposal faces considerable challenges given the current global security landscape. The feasibility remains uncertain, particularly among NATO nations who have heightened security concerns worldwide. The timing is especially complex as Russia has increased its military spending by 41.9%, suggesting competing priorities between diplomatic reduction efforts and mounting security threats that may require sustained defense investments.
