Unverifiable assertion. Benjamin Disraeli became Prime Minister (and one of the greatest) in 1868 with no 'critical mass' of Jews in the UK. There's a far larger 'critical mass' of Muslims than Hindus in the UK. If your belief in cause and effect had any merit, would you not expect the ethnic factor to be a hindrance rather than an aid to the rise of a Hindu to such high office?

In Merry Olde England, they know that getting someone who at least shares their genetics if not their religion is a win for all of them. Once they get some more in they can go back to blowing each other up. For now, they have a common enemy to wipe out...the English.
