In war, it is possible for both sides to lose, and lose badly - so simply pointing out that Iran is suffering does not in any way mean we are moving to achieve our goals.

Absolutely. Just look at Ukraine. Both Ukraine and Russia are "losing". Neither has achieved their goals, both have lost lives and resources, both economies are a mess. Ukraine will both win and lose when Russia finally has to go home. Russia will just lose, even if they manage to keep some of their captured lands in the Donbas (which may not happen).

Iran cannot stop us from doing whatever we want. Just like Vietnam, just like Afghanistan, just like Iraq. Doesn't mean we're winning. They can still strike us, just like all the other examples I gave. We won every battle in 'Nam, but we still accomplished nothing (except mass casualties). Tet? We won. We obliterated them. But we still lost.

I think people keep thinking about marching to Berlin, the enemy gives up, and a new government arises that is friendly to us. That's not how it works now.
