The US and other leading countries had a nuclear deal with Iran, the JCPOA, that was working very well indeed until Trump unilaterally abrogated it during his first administration. The United States was in active negotiations with Iran when Trump and Netanyahu launched an unprovoked attack and now an ongoing war. There shouldn't have been military force used then and there certainly shouldn't be military force used now. The forces roiling the Middle East go much, much deeper than Iran's theocratic government and those forces are more likely to be exacerbated than calmed by more military action in that troubled region.

If you're voting yes, what's the actual endgame here, degraded capability for a year or regime change, because those are very different wars.
