If that's really also the most important demand of Iran then I don't see any peace deal happening.
Because if Iran considers the US bases in the region as a threat to its security at the same time US consider those bases as extremely valuable. Through the presence of this hard power, US enjoys complete hegemony in the region and earn 100s of billions by extortion (oil rich countries spending 100s of billions of dollar on US equipment that's ultimately controlled by the US in the end. That drives US mega defense industry and employs thousands in the US. Also the hegemonic control pushes oil rich countries of region to invest in the US with close to trillion dollars).
So US wants absolute control of that region always. US cannot afford to leave the region as Iranian general demanded. It will be massive blow to US foreign policy and hegemony. US would prefer war but not accept withdrawal from the region.
The middle ground could be that they both decides that few bases to be abandoned like US 5th fleet HQ in Bahrain. That keeps US navy destroyers all in and around PG and strait of hormuz and bases in Iraq and Kuwait. But US will keep bases in KSA, UAE and others for sure.
