It seems like some countries like pakistan and China try their best to reverse engineer even complex weapons systems with fairly good success. The Chinese have taken it a step further by using the diaspora Chinese immigrants who are US citizens working for major US defense firms as a major source of technical espionage. The number of Chinese American scientists busted for transfering American classified technology is quite high. That's only the tip of the iceberg....who knows how many are still peddling secrets who have not been caught. Even when they are caught...its very hard to prove the case. India on the other hand does not seem to be very interested with reverse engineering, but more so because they want to develop everything themselves. Reverse engineering is a great way to close the gap on the learning curve that can take decades. Why cant India take the same route ??
