Starfleet... we're peacekeeping. We're explorers. And somebody tried to use us, use the deaths of my crew to start a war. We fight if and when we have to. Not before.

[I was never going to spare your crew.]

Everything I believe in, everything Spock believes in-- they took it away. And I'm not even going to be there to rebuild. Not in that universe.

[He and Spock have already had that discussion. Even if Jim can change the future, it's already set in stone in that reality. Another alternate universe.]
