The problem is HOW he did it.
Did he reveal magic? Or did he use "technology"? Or what appears to be "technology"?
Because if it's technology and it's seen as a battle over technology and using technology... all that just means is that he might have destroyed the battle force with magic and technology, but has disguised it as pure technology... in which case, he has done an excellent job.
Even if he's crazy enough to declare war on actual countries, as anyone with sufficiently advanced technology.
That doesn't really resolve the issue that some Asian guy put the secrecy of magecraft/the supernatural at significant risk for reasons he is not willing to explain or that he let things get that far when he could have just hypnotized the people he needed to into not ordering the attack.
And that doesn't even go into the fact that he shouldn't even have let enough info get out to provoke the attack in the first place.
Whether he succeeded or not in covering it up, he caused a
major incident which he'd have to justify, because if he didn't there would be no reason whatsoever to keep him around instead of sending the Enforcers to eliminate this potential threat to the masquerade.
And even if for some reason the Clocktower itself didn't investigate, that he also managed to cover up the very existence of the Sekirei means either that not a single magus bothered to hypnotize one of the officials who ordered the attack to find out what Minaka was willing to fight a war over or Minaka erased the memory of every official involved on his own.
Besides the entire thing is just one more incident that shows a major problem with the fic.
When doing a crossover of something like Sekirei with a more serious work, you either have to do lots and lots of world building and changes to one or both settings to resolve all of the issues that come with it to the point where you are basically creating an AU of your own or you just roll with most of it, come up with a somewhat plausible handwave whenever you need one and get people to ignore the issues by making them focus on more interesting stuff like for example the actual story.
Instead of doing either of those this fic comes up with crappy handwaves and then spends an entire chapter badly explaining why this is supposedly not a plothole and makes sense once you think about it.
Basically, if you're not going to actually resolve the issues, don't draw attention to them and just get on with it.
