Yes, Americans should be worried that Russia likes Donald Trump better than America does. Ideally, a president should be liked more by their own country than any other. The fact that it's Russia that likes Trump better is even more disconcerting. Russia's ideals and actions do not often align with American values so the question is: Does Trump align with our American values?
It is scary to think that Russia likes Donald Trump more than the majority of Americans do. This means Trump is clearly acting in a way that is similar to Putin and this should be concerning to Americans, not just those who did not vote for him. Are Trump supporters blind, deaf and dumb?
Americans should not be worried that Russia likes Donald Trump better than America. We have just transitioned from an administration that was so soft and feared to make hard decisions. Donald Trump and Putin are no-nonsense leaders and that why Russia loves Trump. America should be ready a Putin in the name of Trump.
Most people aren't fooled into thinking that Russia or Russians really like Donald Trump. They just know that Trump is a strong leader. They know they can't get away with the stuff they pulled under Obama, Kerry and Clinton. They're just trying to make nice with Donald Trump because they know where he stands.
