I disagree with this statement, given what the British (and French) did all over the world. Thet could -- and did -- divide their colonial possessions into a dozen different entities, carved out precisely to create regional havoc.
We know -- and you yourself argued -- that the regional rulers were itching to go it alone. There was nothing stopping the British from obliging them.
The rest of your arguments are moot once this basic premise is challenged.
Again, whether or not the Independent Kingdoms remained so or not is moot. For all practical purposes they were indepedent. It was the GoI and Patel who forced them to join RoI.
Brits could not have done anything more for them. Yes they could have given them legal independence, but the end result would have been the same.
This can be argued based on the actions of RoI towards those Kingdoms that did not pledge either suzerainty or subservience to British Govt.
We invaded Goa, a completely separate nation.
We invaded Hyderabad, a kingdom that under Law gave its suzerainty to Pakistan.
We invaded Junagarh, a kingdom that under Laws gave its suzerainty to Pakistan.
Heck we took Sikkim 2 decades later as well.
So regardless of whether British gave formal/nominal independence/obliged them to the remaining kingdoms or not, Indian actions would have remained the same. Indeed for practical purposes, these nations were independent.
Patel and Nehru decided that there shall be no independent Kingdom in the Indian landmass. Patel ensured it happened using a variety of means including War.
So if you want to put it that way, RoI was the new up coming empire, regardless of whether Brits gave them independence by name, RoI would still have carried on with the exact same course of action that it did. The result was all the same. 'Join us voluntarily or we will make you' was the GoI mantra of the time.
Bharat varsha is just your version of the glorious Caliphate that once united the ummah, and shall return...
Bharat Varsha is a geographical space regardless of inhabitants.
Ummah is every Muslim anywhere.
