Former US President Donald Trump on Tuesday hailed Russian leader Vladimir Putin’s aggression against Ukraine as “genius” but said the crisis would not have happened under the Republican firebrand’s administration.During an appearance on a rightwing radio program, the hosts asked Trump about Putin recognising two breakaway regions in eastern Ukraine as independent.“I went in yesterday and there was a television screen, and I said, ‘This is genius,’” Trump responded.“Putin declares a big portion of Ukraine — of Ukraine — Putin declares it as independent.
