The US is in the state of being always a few years away from taken over by any interest with money. When the money runs out, it is no longer a few years away.
That is true, but Russia in particular had practically unlimited money to buy off both the US elites and their opposition, due to the rich natural resources and lack of need to support the high standards of living for the Russian population. Only China has more resources but so far they haven't formed a powerful message US politicians can use to rally their constituents to pro-China causes.
