That is probably what he is after. He is the new kid on the block and can get away with asking for an increase in force.
In WW-II, or the Korean war, yea. But the with media telling everyone the war is already lost, and without lowering standards, which the Marines are loathe to do, maybe not so easy, even if $$ were not a consideration.
Plus it takes Congressional authorization to increase the size of any of the armed forces above whatever ceiling Congress has decreed. Think the DemonRats are going to allow that?
So optempo shouldn't be considered? Plus, just b/c congress authorizes an increase in strength doesn't mean willing applicants will be immediately found. In the meantime those same Marines who've been burned out by all these deployments will continue to be burned out.
But I'm sure the answer is as easy as you say.
