There are roughly 30,000 U.S. troops in the middle east region.

The U.S. has roughly 900 troops in Syria, in small bases such as al Omar Oil field and al-Shaddadi, mostly in the northeast of the country. There is a small outpost near the county's border with Iraq and Jordan, known as the Al Tanf garrison.

There are 2,500 personnel in Iraq, spread around facilities such as Union III and Ain al-Asad air base, although talks are ongoing about the future of those troops.

Iraq has been trying to get U.S. troops to withdraw for years, but the Pro-War Uniparty has fought it every inch of the way. Back in 2020 the Iraq Parliament voted for the U.S. to leave, but the Trump Administration flat out refused to even discuss it.
The good news is that the Biden Administration has finally agreed to talks about our eventual withdrawal from Iraq “as long as nothing disturbs the peace of the talks,”.

Since ISIL lost its hold on Iraq, officials have called for the withdrawal of coalition forces, especially after a US air strike in January 2020 killed Iranian top commander Qassem Soleimani and Iraqi militia leader Abu Mahdi al-Muhandis outside Baghdad airport.

Iraqi officials have complained that the US attacks violate its sovereignty.

As for Syria, the government there never agreed to let us occupy a third of their country, which makes it an invasion. And Congress never passed an AUMF, which makes it illegal. However, Congress has voted to refuse to pull out the troops, just last year.
In Jordan we have hundreds of U.S. trainers
There are U.S. bases in Qatar, Kuwait and the UAE.
Just this week, a whistleblower has stepped forward and exposed how the U.S. has refused to leave Niger, despite the new government demanding it.

The Biden administration’s refusal to withdraw from Niger despite an order from the post-coup government to leave has put US troops in the country in danger, a senior Air Force leader said in a letter to Congress that was obtained by The Washington Post.

The whistleblower said that senior officials at the US Embassy in Niger have “intentionally suppressed intelligence” to maintain the “facade of a great country-to-country relationship” as the US is trying to figure out a way to maintain its military presence.

The Nigerien government, known as the National Council for the Safeguard of the Homeland (CNSP), said in March that it was severing military relations with the US and that the US presence was no longer legally justified. US officials have claimed they didn’t receive an order to exit the country.

The whistleblower said that US personnel have had their deployments extended because Niger is not approving new visas for troop rotations. The airman said that all “US forces were scheduled to end a six-month deployment early this month when relief forces arrived.”

There's over 1,100 U.S troops in Niger.

For some reason we maintain the delusions that our troops are necessary for stability in the region.
20 years in Afghanistan led to defeat. The invasion in Iraq led to hundreds of thousands dead. AS for containing Iran, that's been a disaster too.

In Iraq, the Iranians made significant inroads in Iraqi politics after the US overthrew the brutal Iraqi dictator Saddam Hussein who nonetheless provided a bulwark against arch-rival Iran. In fact, Sudani relies on support from the Coordination Framework, a coalition of parties allied with Iranian-backed militias. Iran also has a secure, four decades’ long alliance with Syria, where Assad’s forces have regained most of the country courtesy of scorched-earth tactics, Russian air power and Iranian-backed ground forces. The notion the US could reduce Iranian influence there was always a heavy lift.
