I need evidence for all the "many cargo ships full of weapons coming from Iran [which] have been confiscated". Last I heard there's a blockade of Yemen by the Saudis so it's Saudi incompetence which lead to Saudi defeats in battles. Should have worked harder against the rebels rather than bombing Yemeni civilians and their infrastructure.Really, do you know how many cargo ships full of weapons coming from Iran have been confiscated which means there are a lot more that have gone through? The US spends 700 Billion USD on its military budget and yet they have failed against the much weaker Taliban and the same goes for Pakistan. Although the Taliban have only a fraction of the weapons available to the Houthis.
There's also a big difference between the Afghan Taliban & TTP (Tehreek-e-Taliban Pakistan), one is a actual movement made up of the natives of Afghanistan while the other is a foreign funded terrorist organization. Your lack of actual knowledge on the subject speaks volume.
