There will be no war after September... as winter sets in..Escalation has already happened at Indo China border and NoKo and SoKo border. Seems China is ready for the skirmish. India wants delay and to counter India's delay tactics, they have intentionally took a colonel. India is not in position to fight for now. India needs to concentrate on the Corona crisis.
But now things are very much clear what Chinese want. If possible delay till september and build and prepare.
