Again, your country and your tacit support of an illegal invasion is what made ISIS in the first place. There are warnings already of what could happen if Saddam was toppled but the clanging sounds of coins and the alluring green dollar notes to grab Iraqi oil, drowned and blinded all the warnings.
the material destruction and collateral casualties are left to others to clean it all up.
You're lies aren't even convincing, like why do you think America spent so much time there after Saddam was deposed? They were pumping billions into the country trying to stabilise it.
And all the cost with nothing to show for except for few oil companies to profit? The trillions of dollars that could have gone to healthcare and housing? A wasteful and illegal war that became the sticking point to populism, which led to Donald Trump because you support imperialism? Fascism is always the next logical step of economic liberalism. The liberals love of money always leads to imperialism with the end result being the undoing of democracy.
You reap what you sow. The world may get collateral damage, but the imperial boomerang you threw always comes back to hit your head, and that bump on your head is fascism in the form of Donald Trump.
