They wanted to destroy Russia economically, not militarily, you know, the usual "bog them in forever war and sanction them to death because we control the world finance systems" and it had a good chance of success, but they miscalculated since Russia relations with China and global south in general proven to be much more robust. It was also first time after 1991 so many countries just told US "no" when they demanded another country be destroyed economically. As result BRICS managed to build their own alternative for US controlled finance system, which is pretty ad hoc by now, but it already works and is being strenghtened.
