Some people (especially Indians that's bruised from the April incident this year) has taken glee that China didn't respond.
But what if next week the US sends it's bombers and Chinese fighters escort it? What then?
China could gradually step up its escort of foreign aircraft instead of doing it in day 1.
Just because we didn't escort it immediately doesn't mean it won't happen in the future. As our capabilities rise, we will have more options in our foreign policy.
Some people seem to think just because the US sent its bombers into this ADIZ zone that somehow it will stop China and be scared off
Got news for you, this incident won't stop China's military build up whatsoever, in fact it might even act as a catalyst to speed things up and increase military spending and speed up development.
People forget the 1996 aircraft carrier incidents were the catalyst for the current military build up. If that incident didn't happen I doubt China would be have the military build up we are having right now.
This could be a blessing in disguise for China when thinking about the long term and not just the short term emotions.
