a good point but,i think,apples and oranges. yes we can and have moved stuff all over. however,never against large meaningful resistance. ww1 still some u boat menace had reduced by 1917,almost 0 in 1918. ww2 we met basically no resistance in our island hoping until within coverage by japanese air-phillipines,okinawa. prior to that some interdiction at guadalcanal eventually overcome. in atlantic a lot of merchant losses in north going to russia. hitler didn't put enough into u boats and his surface raiders got trashed quickly by RN. we moved stuff into korea,vietnam,mid east with no opposition at all.
yes,our navy is still dominant despite dems meddling. russia and/or china would still make a major transport too costly and we don't have near the capacity we did in 1945 or 65 for that matter. could we beat china's or russia's interdiction efforts? maybe but the cost would be unacceptable and unsustainable. really the same reasons china and russia are not coming here,even if they wanted to. china gonna have big trouble just crossing the straits.
could be wrong but i don't see a target needing big naval for russia. they can supply cuba,venezuela against no resistance but not otherwise. seems true that the PLA ground is huge but untested. reliability? just getting enough troops to asia to fight them is a major problem. we can't recruit enough and sending a new drafted army would prob= a major civil war here. our industrial base is rusted out.
i don't know enough about current latest air to even have an opinion.
