I have heard this like 55565 times, it's weird that our Pakistani brothers tent only to remember the little they gave and totally forget the substantial assistance they got and still getting from Muslim countries. They even blame them for their shortcomings. Throughout history, countries used to exchange knowledge and help eachother, but when it comes to Pakistan it becomes so special and even a sacrifice for Muslim Ummah, given that what Muslims got from non Muslim, Eastern and Western countries, from tech, training and equipment exceed what Muslims helped each other with, put all together. Pakistani Nuclear program was financed by mainly by KSA, and when Pakistan was under sanctions, they didn't find any assistance but from Arab and some Muslim countries, and irony is that they still get it as are speaking and still ignored. Yah, what a brotherhood!
