There is no strategic or actionable value in a broad judgement of "sucks" or "doesn't suck". The point of keeping details secret is to prevent someone from building mechanisms to specifically counter it. Information disparity in war is an advantage because it can cause an enemy to misjudge their allocation of resources. (either they underestimate and are out-powered, or they overestimate and waste resources)
It's like poker. You might choose to selectively give off some information with your expressions, but you'd easily lose if you showed your cards.
> they decided that they wanted to inject aliens into their strategy.
The US military has not entertained the idea of aliens.
However, I am going to hold off on the 'dismissing is the immediate jump to aliens' part as well, purely due to the position of this guy and the specifics of his claims - he was part of a team investigating the subject and so until he's proven unequivocally of lying I'll just assume there might be documentation he has access to that we don't. His credentials line up and it sounds as if the people who vouch for him are the same.
I'll think it's silly to discredit the fact the government wants to study what's being reported in the sky like some people are doing. Beyond that I'd rather not comment because it's safer to discuss the parts we are actually privy to rather than the parts we aren't, until the dude gets charged for lying to congress or some other official discrediting of his claims.
I am for keeping an open mind, scientifically speaking. Entertaining theories rooted in fictional fantasy is not that. There is zero scientific evidence of technologically advanced life outside of Earth. It is a hypothesis that is just as unsupported as anything anyone might make up on the spot. Just because it is a hypothesis people want to believe doesn't make it any more supported than a hypothesis that it is the flying spaghetti monster.
