Its a special military operation, right?

In all earnesty, what does it change to send troops to Ukraine? What did any of these red lines we European were afraid of help?

Should not send tanks, it could start a war.

Should not send planes, it could start a war.

Should not allow Ukraine to attack inside Russia, it could start a war.

I'm all for defending Ukraine, it's just that it would have been good to have the USA on side.
