Russia just solved the 'missile defense problem', Iskander now capable of penetrating NATO shield?

Russia is reportedly advancing major upgrades to its Iskander-M ballistic missile system, incorporating technologies linked to North Korea's KN-23 missile. The enhanced missile is said to feature advanced decoys, heat traps, improved guidance systems, and the ability to exploit radar blind spots, making interception more difficult. Reports also point to the development of the longer-range Iskander-1000, which could potentially strike targets up to 1,000 kilometers away. As Moscow expands missile production and modernizes its arsenal, concerns are growing over the implications for Ukraine, NATO air defenses, and broader European security.
