Israel is the largest undiscussed human catastrophe of the modern era. Trillions of dollars spent and a staggering human cost. Nothing else comes even close.

America has spent more money on Israel than they did on the rest of the world combined.

Aid

There’s the obvious 300+ billion in aid spent over the years directly to Israel, but there’s also other aid that people don’t realize is being spent because of Israel. For example 100+ billion sent to Egypt, the second highest aid recipient, was the cost of signing camp David peace deal recognizing Israel. Billions have also been spent on Jordan, Palestinian authority, Lebanon to regimes that ensure Israel’s safety.

Wars

The US has spent literal trillions on wars on behalf of Israel. Taking out any potential threats, and suppressing countries that might pose any risk to Israeli supremacy

Iraq war, overthrowing Saddam
Cost america 2-3 trillion dollars
Libya, Overthrowing Gaddafi
Cost America hundreds of billions of dollars
Iran, attempting to overthrow the IRGC
America spent 30 billion so far with no end in sight, not counting the cost that will endured by the world due to spike in energy cost and the damage to energy infra
Syria involvement
Hundreds of billions also spent in Syria

That is not counting the billions in damages done to these countries, that’s just how much it cost America to do this damage

Other costs
Intelligence/surveillance/espionage. Hundreds of billions spent on covert operations, information gathering etc in the Middle East to ensure Israel’s security

The human cost

Dead and displaced
Millions of dead civilians because of Israel’s wars. Tens of Millions displaced. Hundreds of millions of lives negatively impacted.
1-2 million killed in Iraq
6-8 million displaced
Hundreds of thousands of Palestinians killed. Tens of thousands of children in the last 2 years alone. 5-6 million displaced
500k killed in Syria indirectly due to interventions, 14 million displaced

Quality of life and sanctions
These wars have caused hundreds of millions of civilians to live worse lives than they needed to.
Iraq pre-invasion
Was a highly developed country. High literacy rates, a strong middle class, free university education, functional infrastructure, one of the better healthcare systems in the Arab world. The sanctions through the 90s already devastated much of that. The invasion destroyed what remained and has never been rebuilt. The 90s sanctions alone resulted in hundreds of thousands of dead children. Madeline Albright was asked if it was worth it and she said yes, it’s a price they’re willing to pay
Iran
Crippling sanctions have been placed on Iran for decades. 85 million are living under brutal economic conditions, deprived of trade, technology. The opportunity cost is extremely high. These are real people, millions living in poverty because of Israel
Libya
Had the highest Human Development Index in Africa. Free healthcare and education. Housing considered a human right. Electricity subsidies. Newlywed couples received government grants to buy homes

Similarly for all the other countries ravaged by/for Israel. The human cost isn’t just casualties. It’s the destruction of entire functioning societies that took generations to build. Now generations are living in shit conditions

The estimated total spent by America alone is 10-15 trillion. Imagine how much better Americans’ lives could have been. That could have funded healthcare, education, infrastructure, social programs. But no, instead, America is 39 trillion in debt, bankrupting its own citizens and destroying entire civilizations to protect that little parasitic entity that already offers its citizens everything Americans and middle easterners are denied. The irony is that israel has universal healthcare, free universities, generous social programs funded by American taxpayers who have none of those things.

This is just a glimpse and an underestimation, the real cost including the opportunity cost is much more significant
