Russia adopted this strategy in Ukraine and Syria respectively. Russian EW capabilities achieved wonders in Ukraine but failed to counter both US and Israel in Syria.The key to defeating the western stealth threat, lay in revolutionary electronic warfare from the ground, sea and air. A country that doesn't have the necessary resources to develop their own stealth fighter program, or have a comprehensively impenetrable Air Defense Network, ought to invest in development of advance electronic warfare systems.
A country with struggling economy and other shortcomings cannot achieve supremacy in this game.
My take? Continue to invest in defensive applications but strive for lasting peace in the region.
