It all became clear when the latest billions of dollars was to "slow the Russian advance".  Like two weeks to slow the spread of covid.  It won't win the war.  It will allow it to go on and on and on.

Peter had been in Police work for 25 years.
Finally sick of the stress, he quits his job and buys fifty acres of land in Alaska as far away from humanity as possible...
He sees the postman once a week and gets groceries once a month... Otherwise, it's total peace and quiet.
After six months or so of almost total isolation, someone knocks on his door... He opens it and a huge, bearded man is standing there.
"Name's Cliff, your neighbour from forty miles up the road. Having a party Friday night. Thought you might like to come at about 5:00..."
"Great", says Peter, "after six months out here I'm ready to meet some local folks. Thank you...!"
As Cliff is leaving, he stops. "Gotta warn you. Be some drinking."
"Not a problem," says Peter. "After twenty five years in the business, I can drink with the best of 'em."
Again, the big man starts to leave and stops. "More 'n' likely gonna be some fighting too."
"Well, I get along with people. I'll be all right! I'll be there. Thanks again."
"More'n likely be some wild sex too."
"Now that's really not a problem!" says Peter, warming to the idea. "I've been all alone for six months! I'll definitely be there. By the way, what should I wear?"
"Don't much matter. Just gonna be the two of us."

National guards from several states are already being used. Using US Army troops would likely require modifying the Posse Comitatus Act.

Then modify it.  The intent was not to use them against American civilians; it was never intended to hinder national defense in the event of an invasion.

I'm not sure how any US legislation can address the internal policies of other countries.

Not legislation. Diplomatic pressure. Good Lord.

Not without getting really really complicated.The bill was negotiated and written by Sen. James Lankford at the request of Sen. McConnell. You can check the record yourself, but Lankford is as red as they come. According to Lankford:
"I had a popular commentator, four weeks ago that I talked to, that told me flat out... if you try to move a bill that solves the border crisis during this presidential year, I will do whatever I can to destroy you," Lankford said on the Senate floor Wednesday. "By the way, they have been faithful to their promise."
You may consider solving the border crisis as higher priority than sending aid to other countries, but Trump needs a chaotic border he can pin on Biden. To that end Trump has posted:
"Also, I have no doubt that our wonderful Speaker of the House, Mike Johnson, will only make a deal that is PERFECT ON THE BORDER."
Requiring "perfect" is enough to keep the problem alive till after the election. Much as I prefer Trump over Biden that political grandstanding means you were never going to see any resolution till after the election.

Are you seriously trying to blame Trump for this?!

Nixon was one of our greatest presidents.  And in that clip, he's not wrong.

why?

Just watch the first ten seconds.  I don’t know what the rest is yet but the first statement hits the biggest, worst problem we have. The one thing that will irreversibly change our country.

Funny how the anti EV crowd has suddenly become a bunch of environmentalists.

I'm going to coin a new word:
neo-environmentalist.  People that are suddenly environmentalists when it suits their agenda but have never given a shit about the environment before.

Nope. Just pointing out the hypocrisy.  I think you already knew that.

After a couple years my phone’s battery only lasts half a day, in three years my hearing aid batteries were not charging half the time, my laptop battery crashed after four years.  Yeah I want a car powered by a rechargeable battery.
