Two things.
First, as a Vietnam Veteran, I am old enough to respect vital, sincere feeling of others who woke up earlier than I that that war was in idiotic expedition in imperialism, the Vietnamese people did not want us there, they wanted Uncle Ho. So if Bill Clinton or Bush sought an exemption...in that war, at that time, that was an honorable thing to do. It was also honorable to serve if that is how one saw things, as I did.
Now, WWII, a full on war against fascism, it would have been a different thing.
Second, Trump is clearly, as the President of Portugal said of him "objectively, a Russian asset".
There is no excuse for voting for Trump that second time, he had shown who he was during the insurrection of 2021.
If you will remember, President Obama had a perfectly good agreement with Iran over nuclear enrichment...but Trump, being greedy for attention, tore up that agreement. Now he wants to make a lot of trouble perhaps kill a lot of people to call himself a wartime President...
It is a war of aggression to attack a nation not a danger to your nation, and that order is an illegal order, by the way. Israel has hundreds of nuclear weapons of mass destruction aimed straight at Iran, so no one can say that the possibility of Iran's introducing nuclear weapons is the danger. Israel has done that in spades.
