Since BP in general lacks positively-inclined Pak-nuanced voices; I thought this was an important comment to highlight.
There was more than Jinnah involved in the ‘Pakistan Movement’ even if it was a one man show when it came to actual negotiations with the British.
Maulana Shabbir Ahmad Usmani was instrumental in mass mobilization (using Islam khatray mein heh! naturally) and countering Congress’s anti-Jinnah propaganda campaign orchestrated by Maulana Husain Ahmad Madani of the JUH. This was the so called Muttahida Qaumiat movement that held that Jinnah and Aligarh Islamic Modernism was more dangerous than an independent India dominated by the Hindus.
In a nutshell, the insurmountable problem was simply this. Jinnah and some others (non-caste Hindus) wanted absolute safeguards for minorities before independence; Congress and caste-Hindus wanted independence first and then would decide whatever safeguards the minorities would get. As a part of this, Jinnah and others wanted a weak Centre and power devolution to the provinces/groupings while Congress (Nehru and Patel but not Gandhi, who was a hopeless romantic when it came to actual politics anyway) wanted a strong Centre and the provinces to have whatever powers the Centre didn’t want.
If you look at the Cabinet Mission Plan, that is EXACTLY what is being offered: a weak Centre. Of course Congress rejected it and Jinnah embraced it.
What must always be remembered is that the Pakistan Movement meant many different things to many different people.
