I understand and I say that may be, just may be, some people did not give donations because of that perception. But the lack of donations does not have anything significant to do with Zardari: Donations can be made in so many ways where the federal govt. of Pakistan is bypassed (if 'corruption' is the consideration).
It is most probably the 'image' of Pakistan, bad global economy, donor fatigue, combined with the stupidity of Pakistani blogspace/media who have spent an enormous amount of time putting down their own President and government instead of actively projecting the plight of the Pakistanis due to the flood.
I urge people to night ride the wave all the time and think through: Nothing good was going to come out of focusing too much attention on Zardari (whose visit, as I say, will probably get more $ for Pakistan than the blogspace's work).
Again, we still need to debate as to why Pakistanis themselves did not SPONTANEOUSLY mobilize the way like they did in Oct. 2005? I dont' think Musharraf galvanized them. I think, at that time, Pakistani economy was good. There were far less incidents of terrorism than since 2007. This year, it looks like Zardari-bashing is the flavor of the day instead of helping fellows. Apathy? Fatigue? Too battered?
