As the US withdraws from Europe under President Donald Trump’s second administration, it is not only reducing its military presence and casting doubt on its security guarantees but also renouncing its de facto (but never formally declared) leadership of the geopolitical West. That means the US is shedding a political leadership role it has exercised within Western Europe since 1945 and within Europe overall since 1990. The obvious corollary is that Europe will be on its own, left to resolve its geopolitical problems and challenges by itself.
