Yes, but you're stuck with him for the duration of the war at least. Trump's prank didn't work and so the war wasn't avoided.The "negative effect of America's war effort" is having a weak stupid Commander in Chief like Biden that doesn't know his ass from a hole in the ground .......................
Now America is making some very big tactical mistakes that is compromising the war effort, by destroying Biden's credibility.
And frankly, it's a credibility that is easy to destroy. Who would have thought it could become so bad in such a short time?
