The Tor is a very dangerous weapon. However as mentioned already, it can be minimized. "I can touch you, but you can't touch me." A lot of our strikes of targets can be, and are, done from 30-40 thousand feet. Once large SAMs and enemy airpower are down, this kind of stuff becomes easy. A stealth aircraft isn't really needed. Smaller battlefield SAMs, MANPADS, AAA, Trashfire, can't reach. Where if the target is fixed, JDAM usually hits inside of 4 meters. The newer gen laser pods for our laser guided bombs... SNIPER, LANTERN ( old but upgraded with more laser reach), LITENING, can use the laser from that high up. With the first combat use of an Air Force Reserve B-52 fitted with a LANTIRN II pod, It dropped a GBU-12 (500lb class ) laser guided bomb from 35,000ft.... about a 55 second fly time. I use the big fat B-52 as an example because the Tor unfortunately cant reach that far for slant range. When you add slant range for something like a JDAM attack or the devastating CBU-105 Wind Corrected Munitions Dispenser, with the BLU-108b sensor fused weapon (SFW) TOR is no threat.
I would give it credit for fast reaction and even being able to engage a munition on the way down, but how long can it keep that up? It emits so something like the latest Block of HARM with geo-locating would be helpful too. Going expensive, the JSOW-A is made for SEAD/DEAD and is low observable ( most likely design tuned against high freq weapons radar ). So against JSOW it will have less reaction time if it doesn't get a visual.
In my opinion, where TOR is dangerous is if it shows up somewhere on the battlefield and a flock of A-10s or Apaches or whatever think they are safe and find they are in the wrong place at the wrong time. For that, I think TOR is a killer. But it isn't going to be especially helpful in stopping the mail from getting through on a strategic strike. Legacys moving on to do battlefield interdiction dropping the weapons I mentioned will just orbit around at 35,000+ ft. and plink heavy equipment like AFVs, Artillery, anything with wheels or tracks, that looks like it contributes to the war or whatever. Unfortunately TOR for trying to stop that mission, is out matched.
