The US didn't do anything serious. It just gave some empty promises, said some good words, and that's what it all took for the coup to happen. Its hilarious and pathetic at the same time to witness how easy it was for the US to disrupt them.
Same. In theory every country in the world is suitable for BRI. In practise though, the problems start with politics. Do they have a stable political system? Even if your bureaucracy is shit, even if your laws are shit, if your political system is stable China can use trade as a way for local businesses to lobby for better laws or better regulations to smooth business, investment and trade links with China.
That's how normal politics work. You have local interests lobbying for their own benefits
The problem on Pakistan is that due to their intelligence agency being under military control lol, the military is basically the leader of the country, has firm control on politics, and they can easily ignore civilian and business pressure. Local interests have to go to the military first and not to the civilian government to argue their case. And what does the military know about economics and business? Nothing!
Which is partly why Pakistan's economy is what it is today.
Unless a major systemic change happens, I don't see much hope with Pakistan. China can invest all it wants in CPEC but if the military leadesrhip coups and destroys Pakistan's economy every decade or so, it won't do much.
It was easy because the military allowed it to happen. In Pakistan nothing happens without the approval of military generals. The Pakistani generals think that they are the ultimate authority with regards to political matters. You are absolutely correct.
