Trump's success in the US primaries is a real treat for Putin. A possible re-election of Donald Trump would not only have consequences for the USA, NATO and Europe, but possibly also for US support in the Ukraine war.

Putin told Russian state media this month that he would prefer Joe Biden to win the US election in November despite poor polls because, unlike Trump, he is “predictable.” But could the Russian leader be serious when he says he prefers the “more experienced” Biden? Or is it all just a diversionary tactic on Moscow's part?
