What can I see from Indian side situation, is that they're not united. Those politicians, news media are pumping their rhetoric to attack their own head of Government, Modi. Boosting China aggressiveness to blame Modi. And make him looks incompetent. Thus force Modi to take more popular decision that may defeat India interest, and perhaps even put them into a very dangerous decision. Like declaring war to China.
This is normal to most democratic nations, as everything based on popularity. Not the decision to move forward the country. A crisis won't make the people united, instead of to blame each others. Politicians won't support their head of government, and bring the crisis down, but rather blaming him, denounce him, etc, to make the head of government look like a fool. Then, if that happen, then how can the leadership move forward to bring the country forward?
Modi will have to focus on protecting himself, rather than solving the crisis on hand. And this reality is dangerous.
