The last time America pushed Pakistan towards democracy, elections were held and the religious party became one the largest political players. They were and are intractably against America. Before those elections, there was no religious party in Pakistan.
The religious party — and remember that before those elections the religious elements never united to become a force with which to be reckoned — added a major complication, headache, factor of instability, and stumbling block for the Pakistani government.
So, for those clamoring for democracy in Pakistan: be careful what you’re asking for. When will be got might be far worse than what now exists.
