With US logistical capabilities, it was not that big an issue. Why not accomodate an ally if it is possible?
The fact of logistical strength and also of secure bases of supply (England in WW II; Australia in the Pacific war, and in Korea, etc.) has been an important factor in US ability to project power away from North America. Pretty much the same with Diego Garcia and Kuwait in the Persian Gulf/Indian Ocean.
It is always a result of sea power and air superiority in conjunction with that.
