No. I’d support the Iran people in any move they made to change their regime. You wouldn’t?

Coherent principle? How about the US, Israel and Russia are unlikely to strike pre-emptively, except in self-defense, (see Israel’s bombing of the Osirak nuclear reactor in Iraq) whereas the Mullahs in Tehran have explicitly stated that they want the Jewish entity wiped of the map.

Israel has pre-emptively stopped 14 acts of terror this month, including 3 suicide bombings. Should they have let them happen and then retaliated?

And of course Iran is infinitely worse than the US in human rights terms. If you can come up with a coherent principle that would allow the USA, Israel and Russia to strike pre-emptively while denying it to the mullahs, I’d like to see (and adopt) it – as I said above.

Are the US are parading missiles in Manhattan with "Death to the Islamic Republic of Iran"?

No.

Is Iran parading missles about with "Israel should be wiped off the map"

Yes.

This bizzare mental process from some of the left, which consists of running down Western democracies as less than democratic and then ignoring the manifest faults of nations such as North Korea, so that they can claim moral equivalency is the most saddening thing about the pseudo-left.

They do not value the freedoms they themselves hold and think a country that throws mixed Chinese-Korean babies into wooden boxes and buries them alive is equivalent in some way to the US or UK.

Stop playing abstract games.
