1.Deploy British troops in areas of high tension esp Bengal and Punjab.
2.Give us our due compensation for having supported them in WWII, in terms of monetary benefit. Instead they set up commonwealth which was simply an eye wash.
3.Push for talks between the leaders. They did not care for that but the british actually wanted India to be divided and thats one of the reason that 1946 talks failed.
4.Why was Wavell's plan put it in the bin?
5.You are right, the british could not force the Raja of Kashmir. But when he requested the British to help, why did they not send troops to help Kashmir. If India had stayed out of Kashmir may be history could have been different.
