I oppose the illegal and unjustifiable war in Iran and demand an immediate end to the hostilities. While I oppose a nuclear-armed Iran, I understand that diplomatic means of achieving that goal are more effective and come with a far lower human cost, just as President Obama had achieved under the JCPOA.

That's quite a bit different than "doesn't support Iran."

The only mention of Ukraine on his campaign website is:

When we act in the interest of human rights and democracy–as in supporting Ukraine against Russian invasion

That's a very standard bad lib take. But that's just the difference between a party worth critical support and one worth a fuller measure of support -- the former has some bad positions! Look at Russia's relationship with Israel.
