Talk about a thin skin.
So how much are we talking about here? Congress authorized 1.1b in military aid to Pakistan. Their GDP is about 300 billion. So. About 0.3% of their economy is military aid from the US. If this were the US, we'd be talking about $55 billion. The cost to rebuild Puerto Rico has been pegged at $95 billion. Houston probably took a $50 billion hit.
It's not like China and Pakistan are reluctant friends or anything.
Pakistan was the first country to recognize China's communist government. China fought a war with India in the 60's and that shit played well with the Pakistanis. China is Pakistan's biggest trade partner, I know they have a bunch of different trade and cooperation agreements.
China has consistently been a good friend while America has been fair weather and unpredictable.
