I mean I am cringing at the level of mental maturity here. Educated people around the world look at tourists as a problem with the noise, pollution, and crime that they bring. But let us just suppose only angels will come to Pakistan. Your country has been unable to handle waste in its biggest city Karachi. What will you do with the additional waste generated by tourists? I mean, how many tourists do you need to generate 15 billion dollars? If we get 1 million tourists spending $15000/- each inside Pakistan, that reaches 15 billion. Now your international travelers are already at around 14 million
That means a 7% increased stress on just your air travel infrastructure. Then there is roads, hotels, hospitals etc. Is your infrastructure ready for this kind of load? Then you have limited destination. How many people are you going to fit into resorts in the Northern Areas? They aren't even accessible all year around.
Then you have world media talking about Pakistan's role in Afghanistan and Indian media spreading misinformation. You have a diplomatic spat going on with the UK. And you Prime Minister has been on record saying women can get raped because of what they wear. You think tourists will come to Pakistan? How is anyone reading this thread with a straight face?
Then there is the pure dung headed, moronic nature of falling down to tourism. You don't have the intellect to produce and sell better clothes, better tools, better hi-tech products, so the zenith of your imagination is to try something where you don't need to engage your brain too much. This is a failure of leadership, and this is a failure of the followers who are brainlessly following this leadership.
