Joe Biden's plans of US military removal from the Middle East could prove disastrous. Many Americans and Arab-Americans are concerned that without US military power in the region, local terrorist groups will gain power and create civil wars or turmoil in the Middle East.
Furthermore, while Joe Biden has stated he plans to remove troops from the region, no plans have been made to cut defense funding. 
Joe Biden and his Vice Presidential nominee, Kamala Harris, have both pledged loyalty to Israel, making their ability to broker peace between Israelis and Palestinians near impossible. 
Joe Biden is not planning on cutting the extra US aid to Israel. 
The United States has historically been a military power and political influencer in the Middle East. If Joe Biden were to abruptly end this stability for the region, it could result in civil wars, loss of life, and political upheaval for the entire region.
