Starting after 2020, so if America wants to stay a spacefaring nation, better build new spacecraft!
Of course, America has some time to humble itself (Obama having been shown as supremely impotent, anyway), and grovel and prostrate itself before Putin, to beg him to take them back, and to end the stupid sanctions, and acknowledge Russia’s ownership of Crimea.
If not, ’twill be very expensive, getting back to space, indeed. If there’s even the political will to build new spacecraft, at this time. Imagine the challenge of trying to get bi-partisan agreement on that, in these divisive, culture-war, red vs. blue times… Good luck with that…
Just kiss Putin’s ass, and save money, America.
