Yes,, Trump is right on this, at least as to the invasion in Iraq, and mission creep in Afghanistan. Perhaps there would be some merit in electing him POTUS if the year were 2000. But it isn't 2000. It's now.
You meant in 2004?
No 2000. After the invasion of Iraq, the Genie was out of the bottle. As Colin Powell said, once you break it, you own it. And we have "owned" the ensuing civil war in Iraq, which goes hot and cold, but never ends, ever since. It was one of the most disastrous decisions ever made by a President.
Well, either way, with regard to Trump, he never actually publicly opposed the Iraq War (or commented on it one way or the other) until 2004, so it's unclear what he actually would have done with regard to the country had he been elected president in 2000. Given that he
publicly floated the idea of naming John McCain as his SecDef during his aborted 2000 presidential campaign trial balloon period, he may well have had a rather "neocon-y" foreign policy back then. Who knows?
