What is the evidence that Trump learns from his mistakes?
He thought the bombing of Libya was a good idea then but he has since learned it was a bad idea.
Listen to his words very closely, he never mentions invasion at least in the context you imply.
Nor did I mention invasion. I referred to the bombing of Libya. However, the real point is that then he thought getting rid of Qadafi would be a good Idea and nothing further would have to be done, but he has since learned it was a very bad idea without doing some nation building as we did in Iraq and he is opposed to nation building so he now understands the bombing of Libya was a bad idea. Clinton, on the other hand, seems not to understand how bad an idea it was.
Sorry to be so picky but here is what you posted: "The invasion of Libya and the war in Iraq, both supported by Hillary Clinton, were also supported by Donald Trump"
First of all there really wasn't an invasion. Secondly Trump had nothing to do with the bombing of Libya, Hillary did. Big difference in what Trump said he would do and what was done. Hillary and Obama have created what Hillary calls the greatest humanitarian disaster since WW2. She says that as if she wasn't one of the instigators.
