Youtube averages 122 million users a day. 10 million views makes it far from something the average YouTube user has seen, let alone the average person.
There's large chunks of the world proving that false every day. For the geographically impared, the simple fact that Phoenix has existed for longer than air conditioning, proves that statement false.
For day to day use, it's just a single number, no one is doing any conversions, etc, with the number. That was my point. There's nothing to remember. Do you forget what 72F feels like? Do you have to scale it in your head?
When it comes to a single number on a scale, whatever you grew up with will be more "obvious". 100F doesn't give me any more information than 38C does. The whole "base 10" thing only matters if you are actually doing some math to that number.
"Intuitive" is a meaningless metric for a single scaled number. Whichever system you are used to will be the more "intuitive".
Also, climate can play into which system feels more useful. Where I live, 100F occurs only rarely (and since air conditioning is almost ubiquitous, not something I'd bother looking out for), while 0C is an outdoor temperature that I do need to be aware of for half the year.
There's a difference between WMDs that can reach the US, and ones that can only be deployed locally. Russia has the former (and a lot of them), hence no invasion.
The two parts are actually Israel and Hamas. If Israel wants peace, there's not much the US is going to do to force them to keep fighting. And conversely, if Hamas doesn't want peace, there's nothing the US can do (short of entering the war directly) to keep Israel from fighting back. It's all up to Israel and Hamas. The US (and Iran on the other side) are secondary players.
