So Trump is thinking of sending Tomahawk Missiles to Ukraine.

Probably not the wisest move he has ever made. The Tomahawk is pretty much obsolete. It's top speed is around 550 MPH which isn't very fast. It is nuclear capable which may cause Russia to launch its nukes should a tomahawk be seen approaching Russia. Of course the biggest problem is the US doesn't have any. I am sure it has a few in the military museums but other than that it will take several years to build even a small arsenal.
