Can someone with climate science knowledge help out with the following hypothesis:

Let’s say the US wants to engineer a nuclear war in the Middle East to “cool” the global temperature for a determined period of time. This can be done by provoking Israel to use its nukes in a “last stand” as it is being militarily defeated by the regional forces, as an example.

According to the climate model proposed by Robock et al. (2007), a regional nuclear conflict in the subtropics that detonated 100 Hiroshima-size (15 kt) nuclear weapons (0.03% of the global nuclear arsenal) could lead to a release of 5 Tg of smoke into the atmosphere, resulting in global climate change of -1 degree Celcius (which would revert the global temperature, at least transiently, back to the Little Ice Age period between 1400s and 1800s, and would also result in significant changes to precipitation rate, crop growth etc.).

Guess what, Israel/Palestine is located exactly within the subtropical band.

Let’s say several hundred millions of people die from the nuclear fallout (far away from the Imperial Core), and hundreds of millions more die to starvation due to crops failure, the global temperature goes down, the global population gets trimmed, reducing demand for global resources, the imperialists subsequently take advantage of the chaos and instability resulted to harvest the capital assets in the Global South.

Is this something that would be dreamed up by the bourgeois class in the Western imperial core?
