Nothing against Pakistanis living abroad legally.
What do you mean by Pakistan can’t provide clean water? Is Pakistan some sort of an animal? Pakistan is just the name of a geographical area. What happens there is the responsibility of people living in it. Would you leave your father if he is no more capable of taking care of you (because of an accident or something, God forbid)? Why do we expect Pakistan to provide for us if we do not fulfill our own responsibilities towards the country first?
Regardless of everything, nothing justifies being a criminal and immigrating illegally.
