What right will we have to criticize Putin if he kills Ukrainian president Zelenskyy?
From a legal standpoint, the US has illegally killed the leader of Iran in an illegal war which our leaders are not even criticizing. They are just accepting that the US takes out a leader they do not like, thereby destabilizing a nation of 93 million people.
International law does not allow this, but if we do not uphold international law, what boundaries do we have left to limit dictators like Putin?
of course they have. The OPs point is that that, and of course kidnapping, are now legitimate actions according to the USA interpretation of international law. There is a lot of this that isn't new: Lumumba and Allende come to mind, but the OPs point is that Trump has resolutely dumped the USA back into that pattern, inviting Putin's Russia to act like the USSR did with Hafizullah Amin and claim equivalence.
figures are of course disputed, but how many innocents do you need to kill for international law to not apply? 1000? 10,000? 100,000? For the first two, it makes Trump and Netanyahu fair game. And: how is killing Khamenei (and over 100 schoolgirls) doing at protecting the people of Iran from the next round of bloodshed? If international law is in the dustbin, who benefits?
See, take it from this old soldier: you have it exactly backwards. Wars are what happen when the system stops doing its job. And wars stop when the politicians get their shit together.
In between these two momentous events it's up to the soldiers.
International law is a contradiction in terms.
