Re: Maharajah Ranjeet Singh
Pashtoons were nuisance creators, and maharaja’s generals, especially Nalwa was against them, Pashtoon invasion of lahore must have caused massacre of punjabis. so they secured NWFP, i think fort of saragarhi and two other near khyber paas was constructed under Nalwa’s command thus restricted Pastoons considerably in their Afghanistan
and Khalsa and Pashtoon standoff remained even in british rule and last one was Battle of Saragarhi by 36th sikh regiment
for today, support whoever is more in support of pakistan. Sikhs are maati ke laal, jiska khate hai uski ka saath nibhate hain, but may be ground conditions might be different in pakistan, I am not aware of their political support to concept of Islamic republic of pakistan, but do let me know:)
