Russia top dog in the Middle East, China setting up bases around the world, Syria a basket case, Obama's bezzie mate being a woman who opened the immigrant floodgates into Europe....the successes just go on and on.....
The rise of Chinese dominance in terms bases, economic support of other nations, etc., was predominantly due to the US invasion/obsessive preocuppation with Iraq/Afghanistan during the Bush years. We turned our heads, and while we were knee-deep in Iraq/Afghanistan we failed to notice the massive Chinese influence in Brazil, among other places (e.g., Indian Ocean, Madagascar and many other African nations). Some folks (though I don't know enough about the causes and am skeptical of the arguments until I know more), even trace hints of Syria's destabilization to the Arab Spring, the latter of which is linked to the Iraq invasion--another Bush legacy. More generally, every administration inherits domestic and international problems. But in your post you are pointing out foreign policy blunders, while the tweet you quote is all domestic. It will be interesting to actually see if Trump is able to further improve on what is claimed (and attributed to Obama) in that tweet.
