Earlier quoted context omitted.
> “The Russians and the French are not going to abandon their rockets and entrust their nuclear deterrent and early warning system to SpaceX.” The United States is certainly happy to (launch military payloads with SpaceX). Having access to far more launch capacity, far more cheaply, is surely a significant strategic advantage. Edit: Added text in parentheses for clarity.
Are the US sending military payloads with non-US rockets?
EU countries, not having a reusable rocket at their disposal, will have to pay through the nose for every launch, discarding the entire expensive rocket in the process.
Of course, that will limit their ability to launch satellites into space: the cost of discarding a rocket is high (let's not even start about fairing dimensions and subsequent limits on payload size). Wrecking a sophisticated machine after each use is uneconomical.
Meanwhile, the US is galloping towards much cheaper launchers. This means that by 2030 or so, they will be able to put orders of magnitude more tonnage onto orbit.
China noticed - and it is trying their darndest to close the gap.
