I don’t think the Pilot is really taking the time to think through all the logical consequences of what he’s saying
Indeed, even if he wants to make war, the logical next step would still be to keep talking to the aliens and learning as much as possible about them. Then maybe trying to capture or infiltrate their ship. Or asking for escort to their system and returning with strategic knowledge about that. Preparing a surprise attack. Things like that.
Destroying the first contact alien ship would be stupid.
