It actually makes sense. Biden supported the Iraq war and all the other fruitless Middle East bloodshed just as Bolton advocated. They are truly kindred spirits when it comes to failed foreign policy and neither of them has learned a thing in 40 years.
Actually the likes of Biden had ample time to have the war on Iraq had they wanted it, but all they really wanted was endless sanctions so they could collect oil voucher bribes indirectly from Saddam through al Khafaji and Samir Vincent. That’s why Clinton never did anything serious about Iraq, and fled with his tail tucked between his legs from Somalia, which was the act of cowardice bin Laden said gave him the inspiration for attacking the US.
