John BoltonColin Kahl's nomination will be a disaster for Israel and the region Why is the Biden administration more interested in confrontation than cooperation?

We're going to want Hunter Biden."
"You can see here that this would be a kind of mutual assured destruction episode that would go on for a long time," McConnell said.
