I'm not sure if he is declining or about the same? At least he got the names right this time. I would half expect to hear about "President Arby's of Nambia" or some shit.
He got the country wrong though. Victor Orban is the leader of Hungry. Erdogan is the leader of turkey...and if I recall correctly those two know each other too.
It's along the level of this insult. At the level of statesmanship you expect from a president of a country, that's not a mistake you make. For someone calling his general election opponent senile, it seems like he's living in a glass house with a slingshot.
