Since you edited your response to talk about Libya I will respond again. I got Trump's position on Libya from Donald Trump himself.
He called for the invasion of Libya from his own video blog, then during the GOP debates straight up lied about it. The man is a pathological liar. And he had the nerve to call Ben Carson "pathologic" and/or a liar? That's why I find it funny that Trump supporters are talking about what happened to "poor Ben Carson" in Iowa. Trump had already destroyed the man through character assassination. Forget losing the presidency. Thanks in large part to Donald Trump, Carson lost all respect. And Trump is proud of the way he destroys people. So spare me the "poor Ben Carson" song and dance.
But back to Trump and Libya and Iraq. Early on I too thought Trump was a non-interventionist. There was a lot I didn't like about Trump, like his support for unbridled imminent domain and his support for TARP, but at least, I thought, he was antiwar. I was wrong. Here's the difference between you and me. I'm actually open to new information regardless of the source. And the new information I received is that Trump is as much of a warmonger as Hillary Clinton or Barack Obama. He's certainly more of a warmonger than Ted Cruz. But worse, he lies about his own positions! And that is what I can't trust. If you can't respect that, tough. If you don't to listen to people you consider to be "Trump haters" then there is an ignore feature and you can feel free to use it. But whenever I see that there are people as uninformed as I was about Trumps warmongering ways I'm going to speak up. Call it a "wall of text" or "fillibustering" or whatever you want to call it. But what I am doing is spreading the truth. And I won't back down.
