Is Biden pulling back overseas troops so he can concentrate on the war that is happening in his own country?

No ... There's nothing more to be gained by staying in Afghanistan any longer. Twenty years is far longer than we should have been there. Personally, I think G.W. screwed up royally when he didn't finish off AL Qaeda when we had them trapped at Tora Bora. Bin Laden got away and going to war with Iraq (over a lie) created ISIS.

      If there is to be any kind of war at home, it will be conservatives who start it. Conservatives have been getting their way for the last forty years. And, the worst of them, Trump's deplorables, are spoiled brats and bullies with guns. Their January 6 attack on the Capitol in a failed attempt to overthrow the government of the United States was their reaction to not getting their way when The People voted their Leader out of office. But, it's a new day in America. And, those traitors no longer have an ally in the Oval Office to protect them.

I think he will send them to Ukraine. 

You'd have to acknowledge the war is coming from blm and antifa not white nationalists 

Piss poor strategy.

Everyone knows most folks in the military are conservatives.

If he wanted to win a civil war, he'd best do it by starting a war on some foreign enemy.

A civil war?
