To the OP, why would the Kazon need to press an attack? With the array destroyed, what was there to gain at that point? Besides the brag factor of defeating an enemy, that is. With the prize gone, so was the need for risking their own necks.
Voyager had just destroyed a "city" ship (coordinating the Peregrine attack, but it was Voyager's op). This no doubt demoralized the Kazon - who couldn't even provide water for goodness' sake, let alone replace a ship.
I highly doubt those stolen Trabe ships were fully occupied considering the Kazon sects were lean and had high mortality rates - and were literally based upon (California) street gang culture. Not Federation-style spacebound cities. Chakotay would not have killed anyone who was not there by choice to live and die as part of that criminal organization - save their children of course, who were well and truly bound to be indoctrinated into that lifestyle, as we saw in Initiations.
My problem with Endgame was that the future had not happened yet for future Janeway to even exist. After it happened, ok - but this was the sort of cheat like saying "I will invent time travel - and to show I've succeeded, visit myself from the future in the next five minutes, to give myself the blueprints of the time machine I will build."
Go ahead - try that!
