Democrat Joe Biden’s faltering performance at the first presidential debate on June 27 has likely left America’s allies deeply concerned. World leaders are sceptic about Biden’s age, health, and ability to win the 2024 US presidential election, Politico reported. Europe, and in particular NATO, favour Biden’s re-election and fear that Donald Trump’s return to office would hurt the alliance and curb support for Ukraine. Meanwhile, some political analysts are of the opinion that Biden’s survival depends on the timidity of his own party.
