They entered the war with Israel when Israel was hitting Gaza, not when Israel hit Iran during the 12-day war or the Ramadhan war.
What did the Houthis of Yemen do for Iran during the last two wars? They fired like maybe 5 missiles overall. And if I remember correctly, they all were intercepted. Should we thank them for firing 5 missiles for us, missiles which we had transferred to them against UNSC resolutions, while they fired over 60 missiles for Hamas?
If they are willing to enter war with Israel and the US over Hamas but not Iran, I think they should ask Hamas, Qatar and Turkey to fund their next conflicts and arm them.
The late martyred leader is now the late leader and martyred because of his policies. He had a chance to build nukes, but refused to do so. I wouldn't call a person who meets with his commanders in his office when the US has already announced they were going to attack Iran wise or even sane. His policies have resulted in the current situation where Iran is facing regular attacks by the US that may very well last months or years.
