How has JD Vance's position on U.S. support for Ukraine evolved since becoming Vice President?

JD Vance has undergone a significant shift in his stance on Ukraine. Before becoming a senator, Vance openly questioned why the U.S. should provide any financial support to Ukraine or have any vested interest in Ukrainian affairs. However, three years later, as Vice President alongside Donald Trump, Vance now publicly questions whether President Zelenskyy is capable of leading Ukraine and whether U.S. involvement there remains a worthy investment. This evolution reflects a consistent skepticism about U.S. aid to Ukraine, but from a position of much greater influence in the current administration, potentially signaling a shift in American foreign policy priorities.
