Dude, how old are you? If you have any sense of history you'll know that other nations' governmental leaders disliking the U.S President and the U.S. is an historical given. The U.S. is militaristic, Americans are crude and culture-less, American history is the history of bullying & genocide, blah, blah, blah. All these leaders have ever been able to do (or can do now) is to loudly bloviate that we/US/President is an inferior lot because that's the only card they have to play. One of the only exceptions in all of U.S. history was B.H.O.; unlike numerous predecessors and hopefully successors, B.H.O. - holding a Royal Flush - gave away all his cards and caved to the other players at the table. World leaders didn't say horrible things about B.H.O. because they didn't have to; they essentially always got the better of him. History will judge him as one of the most shallow, callow, hollow, narcissistic, and inept Chief Executives in U.S. history. #JimmyCarterIsOffTheHook
My suggestion is you spend some time actually studying or working in the field of International Relations because, honestly, you don't have a clue. Your comments remind me of the grad students I went to university with back in the 1980s; with complete sincerity they would say to me (someone who stood watch on and witnessed the barbarity of the Inter-German Border) that the Iron Curtain fences inside East Germany were there to keep out the West. The most charitable thing I could say about them was "naive." In the interest of keeping things civil here I'll extend to you the same charitable assessment.
Update: Here's a perfect, recent example of "other leaders' pettiness":
