"Putin just completed building a huge air force base above the Arctic circle complete with equipment that can launch nuclear missiles all over North America."

Since Russia has been able to "launch nuclear missiles all over North America" since the 60s, what's your point?

In the age of ICBMs, why does the proximity of a Russian airbase matter?

As for "what do roads have to do with global military strategy", you kind of need them to invade your neighbors as Russia has done many times in the last 100 years, but despite the abundance of roads between the US and Canada, we haven't been invaded in over 200 years..
