It’s straight up the M4 highway.
About like driving I-95 up the east coast, except for the bridge destroyed in Philadelphia!
700 miles straight up the M4 highway? 700 miles in tactical vehicles is a huge trek, even without being opposed.
Not happening.
700 miles is really more like driving from Savannah Georgia to Philly. In tactical vehicles. Unopposed by the Russian military that has been asserting recently granted control over him.
Don’t see this ending well for the guy unless he defects to the UK. The DC/London axis is probably offering him a fortune to do so.
