Then why wasn't it attempted!!!
There was a recent cruise missile attack, why didn't Russian fighters intercept!!??
Cruise missiles are to enter the threat zone, they descend.....Cruise missiles are left to air defenses, coming to saturation of air defenses with multiple cruise missiles, IADS is employed. Enemy will run out of cruise missiles before they could destroy all the enemy targets
If something wasn't done in one instance, it doesn't mean it cannot be done!
If I didn't eat pizza yesterday (even when I was hungry) it doesn't mean I cannot eat pizza!!
Russia in general did not do anything to intercept US/UK/France missile attack on Syria (thanks to Trump telegraphing the imminent missile attack, Russia secured all it's assets!). The decision was purely political!
Trump used Russia's no-counter as an excuse to not impose any economic sanctions on Russia (despite his own administration recommending to do so).
Biggest challenge of most cruise missiles is early detection - even when they're flying 500 m above the ground. Unless AWACS or high-altitude-Aerostats are deployed, they cannot be detected early enough to scramble jets to intercept! As such, the responsibility falls on SAMs - as and when they get detected few 10s of seconds before they fly over SAM sites.
Deducing an AAM's seeker non-capability to lock onto a subsonic cruise missile is pure hokum!
Btw....there're a ton of Hollywood movie scenes where a tomahawk missile (launched by rogue elements) was chased by fighter jets and destroyed!
I see a lot of the 'frog in the well' comments on these forums. Fanboys not fully aware of all the aspects making overreaching pronouncements - that are neither supported by facts or science!!
