Everyone rightly likes to crack wise at Joe Biden's innumerable hilarious gaffes, but what if this wasn't a gaffe?

Oh boy.

President Biden told US troops in Poland Friday that they will witness the bravery of Ukrainians fighting off Russia's invasion "when you're there" — making a significant gaffe after he previously said the US must stay out of the European conflict to avoid triggering "World War III."

Biden made the remark while addressing members of the Army's 82nd Airborne Division after lunching on pizza and posing for selfies with dozens of paratroopers at a mess hall in Rzeszow, southeastern Poland.

"You're going to see when you're there, and some of you have been there, you're gonna see — you're gonna see women, young people standing in the middle in front of a damned tank just saying, ‘I'm not leaving, I'm holding my ground,'" Biden said.

Errr...

Naturally, the White House has gone into DEFCON-2 damage control mode:

A White House official quickly clarified that Biden wasn't changing his stance on deploying the military into Ukraine.

"The president has been clear we are not sending US troops to Ukraine and there is no change in that position," a Biden spokesman told The Post.

LOL! I feel very reassured!

Have fun definitely not going to Ukraine, men!
