So inferior that the Israel strike that was supposed to accomplish SEAD turned and fled when target locked by an unknown anti air defense system?
Most (including US) current generation weapons systems have been untested. There is a reason and a strategy for all weapons producing countries doing the same thing. Using current generation systems where their effectiveness can be studied by the enemy is giving the enemy free information.
In other words, using qualifiers like inferior or superior for literally untested weapons(and yes, weapons are untested until used against an enemy) Is purely a faith/propaganda thing.
Russia makes more money from the sanctions being in place from their oil sales then without the sanctions.
That is the definition of failing.
P.S. Russian oil has full reach of the market because countries that should abide by the sanctions aren’t.
