We are sending actual weapons and machinery, which need to be replaced by new weapons off the factory line. One Javelin missile costs $175k.
"In less than a week, the United States and NATO have pushed more than 17,000 antitank weapons, including Javelin missiles, over the borders of Poland and Romania, unloading them from giant military cargo planes so they can make the trip by land to Kyiv, the Ukrainian capital, and other major cities."

I noticed that recently my local dollar store has now become the 1.25$ store. This can't bode well for the future...maybe we are experiencing the fall right now. You wouldn't really know until after the fact.
The US Dollar can only collapse if the federal government defaults on its debts, or institutes currency controls which make it no longer convertible. The government only accepts tax payments in Dollars, so anyone subject to US taxes has no choice but to hold some Dollars.
But getting rid of this "world police" "free world" bullshit will still help a lot. Consider, right now the US military budget is bound to balloon some more because of this war, without us doing any fighting. Military Keynesianism --- chest puffing handshake.
Finally, if are allies can defend themselves, they will have more spine to call out our bullshit with things like Iraq.
