Right, but how hard to point to Guam, and get a few dozen aircraft out that way at Mach 1.5 while the B-2 moseys along?

Who said the B-2 has to fly in a straight line?

True again, but the Tanker has no stealth. Straight line or not, you only need position forces between the target and the tanker. A non-directional course only decreases the range back to the gas. I would expect assets near the tanker, but that too gives away the intended heading of the B-2. If the B-2 drops on NK, war is on, and metal will be flying everywhere, not just along the route home. But, you know this.
