Do you support Trump starting a new war with Iran, or do you not?
I do not, but I'm also not a US citizen nor live in the USA.
Trump, in my view, really doesn't care about US citizens and his actions have now put the lives of all 200+ million at risk 100x more than they already were several days ago.
If other countries 'join' the military action they become parties to the same flow-on effects.
