Supplying or taking non-military action for an opposing army is one of the most common ways of getting dragged into a war — support for Cuban rebels leading to the Spanish/American War, arms to the Allies prior to the Lusitania, cutting off oil to Japan in WWII, military “advisors” leading to Vietnam.
At some point, the enemy understands that they are in a proxy war and decides to cut out the middleman — leading to direct conflict.
There’s a lot of misery in the world.
It’s not our job to fix it all with our blood and treasure…
Not our blood and inky 8% of our annual military budget.
This reduces or eliminates the possibility of American troops fighting a war with Russia in the future.
