They are preparing to do exactly this and we have given them plenty of time to prepare.
Absolutely true, the whole pivoting to Himalayas campaign is a fully calculated move. They have a preplanned document to consolidate all there unclaimed borders by 2020.
They knew we would react, so they tried tactics which are all calculated:
1. Deploying soldiers to block petrols.
2. Deploying more troops to intimidate (backfired since Galwan).
3. Deploying Armor nearby the gap.
4. Using propaganda against us.
5. Laying foundation for pakka infra.
6. When situation got more tensed, they created infrastructure based on these foundations.
7. They are also choosing terrain rich in resources, fresh water, lithium, ore and God knows what.
There whole point to be here for PLA, is to stay here forever. Winter, I don't think they are dumb enough to play this card, why would you come over here at this harsh terrain without preparing.
What they are bad is any surprise maneuver which thwarts there existing plans because now they would take time to react.
Example, they tried at Galwan, we bitch fucked them so we saw there spokesperson, gobar times doing randi rona. Then there generals got changed, because the one who came here, he was tasked to do such thing, it's just a drama CCP playing to show to the world, looks we are more responsible so we changed our dude.
