“Endless war” has always been lefty talking point. ISIS needed killing and the number of military deaths in Syria was 6(!). It is not Vietnam.
The intensity of combat is directly related to your proxomity, safe boy.
And you don’t get to crow about how we had to kill isis when we created it. That’s like one Mexican breaking into your house, and his brother coming by later to sell you bars for your windows.
Nope. Same issues. Vietnam was constantly resupplied from outside their area. Just like iraq, syria and other places in the me. There will always be resupplied fighters and provisions. It will always be endless unless there is/was a complete lockdown on a country.
