Seems there has already been an agreement made to provide these weapons. What's the holdup?

Wonder if there would be a need for an escalation if these weapons had already been provided as promised? Shouldn't there have been a concerted effort to withdraw a proportionate number of American troops for every Iraqi Army brigade supplied with weapons?

A fear that they will end up in the hands of militias? Where was that fear when warehouses full of weapons were raided over the past 4 years we've been in Iraq?

Question: what happened to all the Iraq armoury? What happened to its airplanes, helicopters, tanks armour-vehicles, artillery, machine guns and all the munitions etc etc. Not all of it was destroyed in the invasion - probably not even a significant part of it. So what happened to it? Did a few 'friendly' arms dealers get the lot to sell off elsewhere?
