>>63954700Somewhat. The issue with ICBMs is that preparing them for launch can take longer than their flight time. If you know where enemy silos are, you could nuke them before getting nuked yourself. Soviets/Russia in theory also had first-strike capabilities since late 80s, but IDK how complete they were. This is why mobile (either TEL or submarines) and hidden launchers are pretty important to have, so you can guarantee there is someone to strike back. This is also why putting missiles closer to your enemy is important - shorter time of flight, shorter reaction time and less chance their get their nukes flying.
Notably I don't think China can be first striked because they're simply further away from US, since US-Russian nuclear exchange would mostly happen over the Arctic and to get to China you need to go over Arctic and Russia or over Pacific, the long way around.
>“300 small mobile launchers” enough to only target US cities.It's not enough to only target cities, more like at that point you can only target cities since their nukes already are in your ass.
