There are many similarities except personality. There are still many people who think that the two of them praise each other, which is actually a bit embarrassing for Obama. When Putin and Trump praised each other. Both words and words will make Obama feel that he is "lying with a gun" behind his head. For example, when Trump praised Putin, he often put Obama last and talked about the Obama administration's policy toward Russia.
Trump appreciates Putin's tough foreign policy and domestic iron fist rule, which is very political. What Putin does is actually what Trump really wants to do. From the beginning of the campaign, Trump made no secret of his affection for the political strongman Putin. All kinds of praise, without stint, even offended the establishment, and publicly praised Putin as a better leader than Obama. Although this remark caused criticism at home, he obviously didn't care.
Some people think that Trump wants to please Putin to ease US-Russian relations, but it is also possible that Trump has hidden ulterior motives, that is, his family business interests are related to Russians. Almost every meeting between US President Donald Trump and Russian President Vladimir Putin will stir up some waves. When they met and talked, they were very close and kept laughing. They were accused by American Democrats of being traitors, and the media also gave them abuse and fierce criticism.
