it's obvious that indian army came into Bhutan's territory uninvited and the purpose is to looking for a fight with China.
i think PLA should give what Indians are looking for, after all there is nowhere for PLA to retreat.
it is essential for China and Bhutan to normalise a bilateral relation, the prerequisite to that is to clear india's influence over Bhutan and free Bhutan from India's control.
this could be a good opportunity as indians are pushing themselves forward, just like what they were doing in 1962.
the 1962 war shattered india's ambition over Tibet, i think a 2017 war would make Bhutan a truly independent country.
For the last time we never had our eyes on Tibet.
In 1951, i.e., when annexation of Tibet started...our General Cariappa warned Nehru of Indo China war. Out of Poverty, we couldn't focus on Army and we lost the war.
I'd also suggest you to read about battle of Rezang la, about Maj. Shaitan Singh, about Jaswanth Singh 4th Garhwal Rifles....
Before you ask for Skimmers, I'd like to suggest you that this is the best time if you want skimmers (in North East part of India) with India. We don't have enough Arty (M-777) are on their way. T-72 regiments are located, but they need more time(don't take it granted that they are I'll prepared. They are not prepared compared to high standards of Indian Army). Infrastructure is on its way... second mountain corps is still on paper(by the way existing force is world's best mountain corps, don't take them lightly). We don't have LCHs...so on and so forth....but yeah they are coming. After 3 to 5 yrs, PLA wouldn't even consider that Chicken's neck exists.
Oh and one more thing IA has very bad habit of identifying weaker spots within, train for all scenarios, train till they become muscle memory. I bet IA has trained for all possible scenarios especially for Chicken's neck, waiting to return 1962 with compound interest. The only question is when China will give that Chance!!??
In short, China will never get best time for Skimmers with India.
If you want war, then wait for atleast 7 years from now.
Coming to skimmers, even today India will beat shit out of PLA. If PRC looses face in the hands of India, you won't find a way to cover your face in South Asia. PRC has to make sure to attack only after all Shang and Han class subs on their way to China should pass Malacca Straight (So that IN won't be able to catch them, or it will be huge embarrassment for PLAN. Personally I prefer to sink them, but IN might ask them to surrender(capture them for more embarrassment of PLAN).
In short, buddy skimmers with IA is the last thing PRC want to wish for....
