Do you know that jesus more love isreal not the others people .. so tell me we have to prefer christianity or the buddist, muslims etc..
You should help people despite them being Christian or non-Christian
Mark 12:31 NIV
The second is this: 'Love your neighbor as yourself.' There is no commandment greater than these.
What is important is that it does NOT say, "love your neighbor as yourself, if he believes like you do". Also, I would suggest that it would be against Jesus' teachings to even consider helping someone or not based on their status of being a Christian, Jew, or neither.
There's another way to read the OP's question, which would be, "why isn't American (being a Christian nation) helping Christians in Pakistan?" If that is the OP's intended question, then the question is political and off topic for Christianity.SE. Christians in Pakistan (or any other country) shouldn't expect America to specifically help them due to their Christian status. America is not a Christian nation and is not the leading voice for Christianity. 76% of people in America identify themselves as Christian. Christians generally assert that America was founded on Christian principles and many would assume (but not say) that it is a Christian nation. However, it's just as likely that America has influenced Christianity. For example, toleration of other faiths is not a Christian principle - especially during the dark ages. Does that appear to contradict the above bible quote? Yes, yes it does. Therefore there are differences between the mainstream Christian Church and some teachings from the bible for better or worse. There are too many to list here and I will not engage in a comment tit for tat with anyone over this.
As far as whether it is right or wrong that cannot be answered since it is subjective.
As to why we do it that is easy to answer: We do it because Jesus told us to!
Mat 5:42 through 48 KJV
42 Give to him that asketh thee, and from him that would borrow of thee turn not thou away.
43 Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy.
44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
46 For if ye love them which love you, what reward have ye? do not even the publicans the same?
47 And if ye salute your brethren only, what do ye more than others? do not even the publicans so?
48 Be ye therefore perfect, even as your Father which is in heaven is perfect.
If we do no less than what we are able to do to be as Jesus was, then we are not worthy of being his disciples.
That goes along with his commands 'to do unto others as you would have them do unto you, and turn the other cheek'.
