Why not? It has worked for the B-52.
I worked Minuteman for 9 years while in the USAF and the reliability has been phenomenal. It is getting old and the LGM 35 "Sentinal" is on the drawing board. It will replace the missile in the same launchers currently used for Minuteman.
When I got out of the USAF I went to work with Martin Marietta on the LGM 118 Peacekeeper (M-X) program that was a very capable system (CEP in your living room type accuracy) that could use mobile launchers.
Congress really s#!t on us with that one. It was a great system and the dims killed all attempts to really make it a viable and ultra survivable system. They sold out to the "peace at any price" crowd. It also wound up being based in former Minuteman launch Facilities before it was prematurely retired.
As far as Russian hardware...you see the products in the current action in Ukraine. Not impressive. The Chinese are also on a learning curve that shows they have a ways to go before they pose a threat to a hardened target at intercontinental range.
