Given the disease aboard the Exeter, destroying it would have been the prudent thing to do.
The Excalibur could have been repair where it was to the point it could have gotten to a repair facility under it's own power. Otherwise it would have had to have been towed. Depends on what was actually wrong with it.
Every time the Federation Council is featured in the new series, it should be like a episode of House of Cards, with some Throne of Swords thrown in too
