In Indian scenario... For throwing away a party in power in Delhi in Bangladesh style... The crowd encircling/attacking Delhi should be multi-ethnic/multi-lingual(not like khalistani farmer protest which badly affected other communities)... it should be a Pan-India massive discontent much more than what Indira gandhi faced during emergency... & most of all... opposition should be ruling atleast some of the four states that border Delhi viz. Haryana, Rajasthan, MP, UP. Otherwise crowds from opposition ruled states won't be allowed to pass through. All four currently are being ruled by BJP.
I mean no disrespect but such a crowd coming from south of Vindhyas is simply ruled out.
Last time the people who came from south of vindhyas were Marathas and they found massive support in North bcoz Mughals were enemies of all.
Now some member(s) were raising question whether the Indian army generals will support GOI in such case?
The Gernails won't be needed. Why? The early congis were visionary
**##... They created the CAPF's for this very purpose... though this purpose was not exclusively stated. There are a million+ CAPF & the BJP ruled states bordering Delhi too have their police forces & if ever such situation arises there will be a counter mobilization of BJP/RSS Cadre.
75%+ of such crowd... if it ever appears will be made up of Mullahs & Bhimtas... that in itself will irk majority of the Hindus especially in North. Counter mobilization would be massive.
So the prevalent conditions are not suitable for a forceful overthrow of BJP.
(**##Like Bhallaldeva said before going against/killing his mother Shivagami devi...
"Phir Main to itna neech hoon... apni suraksha ka dhyan nahi rakhunga". Same way early congis did all arrangements to avoid such situation)
