How is the US having accurate weapons unethical? These hypocrites never seem all that concerned about the war-making capacity of China, Russia, Iran, or other rogue states.
And then we could argue the whole premise of "we have to do it because the others are doing it" which can be used to justify everything.
The result has been 3 decades of near continuous warfare in countries of little strategic threat to US interests. As a peer competitor to the US, do you fear a smarter drone or an ICBM?
In contrast, Iran, China and Russia do not on a daily basis assassinate civilians with missiles.
Those countries do, however, do a whole bunch of other pretty bad things.
And I definitely do not want them having more power an influence to enact their agenda on other parts of the world.
Because we sell them to despotic regimes like Saudi Arabia who use them to do things like kill innocent people in places like Yemen?
(Also, what does "hypocrite" mean, in your view? I'm used to it meaning "one who denounces behavior in others while engaging in the same behavior themselves," which doesn't seem to apply here, I think, since the person in question ceased engaging the behavior he denounces, and as you point out, we have no record of him denouncing anyone else doing it.)
