As Trump gains momentum, Europe braces for a future without its most powerful ally I DW News

The so-called Super-Tuesday has made a November re-match between Donald Trump and Joe Biden almost inevitable. Voters cast ballots in 16 states and one overseas territory. With no substantial opposition in his Democratic Party, Biden's string of victories was a virtual certainty. Trump's wins helped cement his overwhelming dominance over his one remaining Republican challenger.

With another set of Trump primary victories, the likelihood of a second Donald Trump presidency looms large. That's made European leaders nervous - and vigilant. The possibility of a return to an 'America first' policy in Washington and even the lack of support for NATO has forced officials on the continent to prep for a future without their most powerful ally.
