"One widely cited estimate shows that the U.S. spent about $2.3 trillion in two decades in Afghanistan,

from fiscal years 2001 to 2021. That’s from the Costs of War project by researchers at

Brown University’s Watson Institute for International and Public Affairs.

That’s $2.189 trillion more than the $111 billion in aid given to Ukraine."

$2.3 trillion divided by 20 years is about $115 billion a year.

First year Ukraine $111 billion.

If the Ukraine spending continues like this per year it would be similar to the yearly spending in Afghanistan.
