The above map is produced in Global Times and showed the flight path taken by the B52 bombers on 27 Nov 13. The heading of the B52s directly into China is an act of hostility. Given the capability of the B52s, at 200km off the Chinese coast they are able to launch cruise missiles to strike at Chinese coastal cities like Shanghai or Xiamen. As China was not given a flight path and the intent of the bombers unknown, it could assume that they were enemy aircraft with hostile intention.
Given such a scenario which was aggressively provocative, China should have scrambled fighters to intercept the bombers and force them to turn around, firing warning shots if necessary. China should lodge a strong protest to Obama (and the UN) and warning him that any military aircraft heading towards China unannounced and crosses the 200km (or 300km red line) would be declared as hostile, an act of war, and would be shot at.
With this nasty experience, China should make this clear to Japan and the US and its allies that China will take military action to shoot down unidentified aircraft acting in a hostile manner with no exceptions.
At the very least China must scramble its fighter to intercept and force any military aircraft to turn around. This is a military protocol that all nations will adopt in the face of an intrusion by unknown aircraft. The B52s are not any civilian aircraft but nuclear capable bombers and getting anywhere nearer is a very dangerous and offensive act and cannot be repeated.
The Russians shot down a civilian airliner from South Korea when it claimed to have lost it direction and flown into Russian territory. In this case, the B52s cannot be allowed anywhere nearer than a 200km radius from China's coastline. The Americans are playing with fire.
China should also raise this issue at the UN Security Council and make its stand clear, that it will shoot down military aircraft encroaching into its airspace and within a specified distance that would allow it to conduct a strike against China's mainland. This message must be made known to all countries and the American's irresponsible act must be registered with the UN that such an event had happened and would not be allowed to do so again.
The stupid act of the Americans could have started a war yesterday. A hawkish Chinese general could have fired a SAM at the B52s as a defensive act and rightful to do so. The Americans were acting irresponsibly and in a very provocative manner. This was how close the world came to the Third World War should the bombers be shot and brought down.
The crazy cowboys must not be allowed to try this again.
