"There's no way that ANY defensive missile system or jet fighter will take out an ICBM - they travel way too high & too fast..."
That turns out not necessarily to be the case.

"The S-500 is a new generation surface-to-air missile system. It is designed for intercepting and destroying intercontinental ballistic missiles as well as hypersonic cruise missiles and aircraft, for air defense against Airborne Early Warning and Control, and for jamming aircraft. With a planned range of 600 km (370 mi) for Anti Ballistic Missile (ABM) and 400 km (250 mi) for the air defense, the S-500 would be able to detect and simultaneously engage up to 10 ballistic supersonic targets flying at a speed of 5 kilometres per second (3.1 mi/s; 18,000 km/h; 11,000 mph) to a limit of 7 km/s (4.3 mi/s; 25,000 km/h; 16,000 mph). It also aims at destroying hypersonic cruise missiles and other aerial targets at speeds of higher than Mach 5 as well as spacecraft. The altitude of a target engaged can be as high as 180–200 km (110–120 mi)".
