> And if anyone launches a direct attack on the US, they’ll be attacked with nuclear weapons in return. Hololens wouldn’t help the US at all for self defense, only for action involving deploying troops.

So you're saying the US should have nuked Afghanistan? I think you have an oversimple view of international relations and military affairs.

Nuclear weapons weren't necessary for that job, but the outcome was the same: the removal of the Afghani government through military force.

No. An obvious solution to the afganistan problem is to simply cut off all immigration from that country.

Or enact similar immigration restrictions, like Trump did about a year ago.

Deploying troops is far less genocidal than dropping nukes, don't you think? I'd much rather us the former than the latter.
