... Their army can do nothing against the Marines ...

While I do agree Iran's ground forces are feeble against the US Marines, providing Pres trump is actually listening to his Generals about the Marine deployment.

That aside, I still have some questions...

For starters, Pres Trump has said he already won this war. So, why is he still fighting a war he won?

OK,I'll start there...

@#3 ... how come our marines couldn't beat the taliban after 20 years?...

As I noted in my #1 comment.

...While I do agree Iran's ground forces are feeble against the US Marines, providing Pres Trump is actually listening to his Generals about the Marine deployment. ...

So, my view is that the Marines are up to the task, but they seem to be held back (OK, weakened) by how they are deployed by the Commander in Chief.

imo, it is not about the level of force, but how the force is or is not deployed.

@#7 ... The only way to combat guerilla warfare is to treat the entire population as the enemy. ...

Sounds like a lesson the US may have learned in Vietnam back in the day.
