If Nepal is allowed to issue 1.3 trillion USD in debt every year then they could become more powerful than USA and perhaps the whole world. Now you could order Aircraft Carrier or fire million dollar missiles on donkeys in Afghanistan, one day this fun will all finish. Same is valid for PakistanI don't think so. USA has a very high credit rating which means they pay very little interest rate on their loans. So you cannot look at their loan as a negative thing like you do in Pakistan. For example if you are paying less than 1% interest rate on $100 loan, and you are making 5% profit from investing the loan, you are getting net benefit of $4. So the loans are actually a privilege that these countries with high credit ratings can enjoy.
Also compared to the size of the economy of these countries this debt is nothing. The US tax revenue is $3411 billion, and the interest on the loan they pay is only $364 billion. So this is around 10% of their budget. Compared to Pakistan we spend half of our budget on servicing debt. (Pakistan pays 9th highest interest rate on External debt)
US has made an order for 1,500 Stealth fighter jets and orders 5 Gerald R Ford Super Carrier. Each Gerald Ford Carrier costs $14 billion+, this is more than our entire military budget and 4 times more expensive than Nimitz Class Carrier. So they are definitely not going broke, nor losing power.
