Partly true. You need a concerted air defense effort like the one we had immediately after 9/11.
However, in an era of look-down-shoot-down radar, the best UAV platform is probably an F-14 carrying AIM-54 Phoenix missiles; next best is any 'teen series fighter (F-14, F-15, F-16, F-18) loaded with AMRAAMs.
In an air defense emergency, the rule of thumb would be quite simple: if it flies, yet does not obey orders to land IMMEDIATELY, it dies.
Attack helicopters cannot cover the distances involved very rapidly, and they don't carry longer-ranged radar-guided weapons.
