Can it hit us?

[vegabook]

Absolutely. Submarine launched and with 10000km range it doesn’t even have to be in open seas. Now France would get obliterated too in response but we’re talking a scenario where the US has already « deleted » Italy so the game theory leans fatalistic

Modern nukes explode high in the atmosphere, so "hitting" is not very difficult. They aren't exactly precision weapons.

[ceejayoz]

They are quite precise - a hundred meters or so. Air bursts just do more damage.
