Well Britishers used to call us Emotional fools.
I do not agree with you...Rather i feel, in general, people of Pakistan are very good at their heart...And the reason of being so good at their at heary due to their acceptance of relceigion as the primary motivator in their life...So usually people of Pakistan thinks more by their heart than mind...(Just keep India out of the equation)...That is why, you see, many Pakistan people provide emotional response to all the threads than tactical descisons.
Coming to this topic, the expectation of SA is nothing unexpected...SA may not have sent forces to fight with Pak army when Pak is at war with India, but they have helped them in so many other countless ways, that Pakistan can not deny them...Sending some thousand soldier is not a big deal...Rather helping economically to Pakistan at the time of war is the critical thing which SA has done for Pakistan.....
The reality is that in the 21st century, Pakistan got another source of money than the gulf nations...which is China...So now the advantage is on Pakistan to milk both Arabs based on the interet of Pakistan rather than based on the interest of the Arab nations...Because of the cushion from China in economic fronth, Pakistan would able to say no to their closest friend like SA...Otherwise, they could have exactly done as required by SA if China is not backing SA in this descison.
How come from one kind there are couple of million princes?With a couple million princes to chose from, why should anyone be surprised?
