Let's just forget the Finance issue look over the whole problem
1 What makes this a Pakistan problem? Palestine Spat in Pakistani Face and supported India not just recently that has always been the case.
2 Land Route Unless Pakistan is sending Warships how will you send supplies or anything through Arab countries will they openly allow this?
3 How this step will be taken by the international communities Israel has a strong lobby in the US and EU.
In the so-called War on Terror how many countries gave funding to Pakistan and weapons and intel. ( IT was uncle sam - they had their own agenda but besides China, and some Turkey support majority did nothing heck not even Said words of support Pakistani people were dying and beloved Muslim brothers DIDNT GIVE A FLYING F***)
4 Did any country send its soldiers to fight TTP or for Pakistan?
What Makes Pakistan so special that they have to fight for everyone.
5 Every Major Issue in the last 60 years regarding Muslims, Pakistan has been involved directly or indirectly.
Which has only caused a problem for Pakistan instead of building international relations.
The Best thing Pakistan can do for Pakistan & Other Countries is to build its Economy & Military power , Muscle flexing will only work when Pakistan has strong trade with other countries and have money in the bank to support its ambitions. Pakistan is a 200 mil+ country but doesn't get treated like one.
