Iran doesn't really have any military projection. It can't even move equipment and people into countries it's close to (Syria, Iraq), let alone the US. Why would they take the risk of doing this? It's obviously bullshit.
I'll take "things people said about Afghanistan in 1999" for 400!
Just to be clear, I fully agree with your sentiment. Probably not Iran or any other foreign power.
A lack of military projection doesn't mean that your country can go in and rout out all insurgency. It just means that Afghanistan isn't going to be able to wage war on US soil from Afghanistan.
likely, until theyre crying everything is antifa again. they seem to cycle around through their paranoia targets.
Certain people will try and drag you into an Iranian war, but I don't think it will work now. The playbook has been used too many times.
