John Oliver kicked off Sundays Last Week Tonight by mocking President Trump for his justification of avoiding the use of the word war amid the United States military operation in Iran.

The Iran war entered its second month, though Trump tries not to use the word war for reasons he probably shouldnt be saying out loud, Oliver said, setting up a clip of Trump explaining why he isnt using the term.

I wont use the word war because they say if you use the word war, thats maybe not a good thing to do, Trump said. They dont like the word war because youre supposed to get approval, so Ill use the word military operation, which is really what it is. Responded Oliver: What? He really just talks like a 6-year-old speaking stream-of-consciousness to a stranger: And my mum says Im not allowed to talk about my penis with other people, even though everybody has one, well, not her and not my sister, but my dad and I both have penises, but I cant say that when there are too many people around, even though everyone knows cause they have their own penises unless they dont, but I do.'

Oliver then said that no matter what word is used to describe the conflict, it has been chaos. He recapped recent developments, including Trump threatening to attack Irans power grid if the Strait of Hormuz remains closed, posting on social media that hed be starting with the biggest power plant first. That would be a war crime if this was a war, but luckily we now know it isnt, Oliver observed.

Oliver continued that Trump then said those strikes would be delayed after fruitful conversations with Iran, which the latter denied have even taken place. Trump then extended the deadline to April 6, though Iran has been bombing U.S. bases and allies. He noted that 2,000 Iranians and 13 U.S. service members have been killed so far, while Trump is reportedly mulling sending another 10,000 troops to the region.

It sure feels like were in an unnecessary war with no endgame, though the presidents supporters will insist that if you just look at things in the right way, it all makes sense, he said, showing a clip of Louisiana Sen. John Kennedy, a Republican, giving his take.

Heres why we went into Iran: We had no choice, Kennedy said. The president didnt start a war. He was trying to stop a war.

Said Oliver: Oh, I get it. Sometimes you have to start a war to stop a war. The same way you have to spend money to make money or fake it til you make it you know, any of those things that people say when theyre in way over their heads.
