It doesn't really matter if he sees them, he already knows he is a disingenuous twat. The reality is his followers will see only the tweet as they scroll on by and this response will be somewhere under the fold mixed in with all the bots and simpletons circle jerking about how "true" this tweet is.
This is why these Twitter gotchas don't mean anything. Yelling into the void doesn't break into other people's media bubble it just tells the algorithms that this tweet is getting engagement and should be bumped up.
Honestly if they spend that on weapons and then use it lower the population it could help.
Shoot maybe Thanos was right...
