Pakistan want good relations with everyone, kashmir issue is not because of muslim brotherhood but because of Jinnah statement that Kashmir is an integral part of Pakistan. Second Pakistan should have relation with Israel atleast a fair relation, it can not be brotherly, Palestine cause should always there and it can be well negotiated after having relation with ISrael. pakistan also proposes a peace resolution with the help of Turkey, Malaysia, Egypt and other 4 countries in 2006,
I can tell you one thing more Israel want relation with Pakistan and they tried everything to make it possible, interestingly both of them met in US secretly.
Peolpe of Vygur (sinkiang) are chinese nationals so it is not Pakistan concerned, Kashmir is a different thing due to partition.
Palestine issue is because of illegal occupation of Israeland now even pakistanis are thinking that we should accept the reality because the peolple now living in Israel are born in israel and they are not migrators.
