In Ukraine itself and among America's NATO allies, there is disbelief that in a United States with still-strong public support for Ukraine, and two Houses of Congress that reflect that support in large, bipartisan, pro-Ukraine majorities, 60 billion in renewed military aid for Ukraine may remain forever blocked. The reason is that Donald Trump, now the front-runner for the forthcoming US presidential election, wants to deny President Joe Biden a political victory and has prevailed on House Republicans to grant his wish. If America's democracy is on the ballot in the election, so, it would seem, is its global power. Even if Biden is re-elected, the Ukraine impasse suggests that may not be enough to salvage either.
