Add up the sh1t Iran blew up within the hour after the attack. 11 countries, multiple strikes. Oh, and they took out the long range radar guarding Israel. You're also completely ignoring repair and rebuild costs. And whether I'm right or not about the costs does not change the fact that Trumpedo is a traitor, rapist, murderer, and pedophile, as well as a financial criminal. Again, bad math has nothing to do with Trump unless it's Trump's math. No part of calling the math horrendously incorrect means Trump isn't a traitor, rapist, murderer, and pedophile, as well as a financial criminal - you just treat anything but absolute agreement with everything you say as defending Trump.
If we are to "add up" cost to other countries then its not exclusively US military expense and there is no reason to compare that to the US Education/Medicaid/Healthcare system. The statement clearly implies the US could be spending USD on Universal care "for decades" instead of a war with Iran - versus total cost
to all countries could cover the cost of US Universal healthcare/Medicaid/Education for decades. Even with US aid to rebuild it would never get remotely close.
A war with Iran will cost the planet more than a decade of Universal healthcare in the US? Let's say then that a war in Iran will cost more than a Century of free healthcare in Mexico, or 800 years of free education in Somalia.
The Iron Dome cost, from inception to use, won't cover US Healthcare for one year. Even if we double the battery cost to 100 million, each, that's barely a Billion in deployment cost and Iran did not disable all of it. If Israel had
1000 more of those you would have 1/40th of one aspect of US Universal care described in your math.
