What was the point of the Belgorod Raid? And was the USA behind it?

On Monday morning, a saboteur group allegedly made up of Russian nationals attacked several Russian border towns Belgorod. The Russians, obviously, responded with overwhelming force, and after about six hours of fighting, the saboteur group was defeated. Vehicle crews retreated back toward the border and abandoned their infantry to be killed or captured. I think this was an American-planned operation, and I’ll explain why.
