Even Hillary is American. And Trump has said before that he likes Hillary and thought she would be the best person to negotiate a deal with Iran. Considering his praise and donations to democrats, what makes him such a better American than, say, Hillary?
Holding American citizenship no more makes you "American" in this sense than a Frenchman holding German citizenship makes him German.
This is where I draw the distinction between a Donald Trump, and a Hillary Clinton.
Now I've already answered your question regarding "praise and donations." They were a function of playing a part for the circles for which he wanted access. You do not have to approve, nor agree, but you certainly can not, with any degree of intellectual integrity, dismiss my rationale as "ignoring his history."
As we now seem to have gone full circle I'll close this dialog with hopes for your good fortune and health.
