How did this joker become president in the first place? And when did he become Putin's agent (I guess during the years he 'retired' from the politics)?
God knows, he had good PR I guess. His PR was he wont be the same as he was when he was a PM (he was crazy back then too), but look and behold he's 100 times worse now then when he was a PM. Its not just that he's crazy, he's doing a massive damage to our foreign policies, Plenković needs to go around explaining what he said, what he meant and basically that he's a lunatic.
As for being Putin's agent I think it's cause he wants to be against everything and everyone and controversial and hates Plenković's guts (and vice versa). So if Plenković is pro Nato, pro EU and pro Ukraine he'll be dead against it even if it means its doing damage and despite the fact its completely insane to have a president and PM with completely different views on global politics.
Its that and maybe he's on a Russian payroll.
He's now cited in Serbian pro-Vučić tabloids too cause he said Kosovo was abducted from Serbia. He had different views when he was a PM of course.
We had a Mesić for a president for 2 mandates too, he's prorussian too, God knows why people elected him not once but twice.
