See bold above:
1) US's law makers and politicians come from real educated backgrounds and an established system that keeps getting mature over time, and has been for decades. This is the MAIN point. The military in Pakistan has never allowed such a system to be created and mature over time. Ever time there is the "Democracy", its after many years of Military rule so you can't really do a whole lot when you have to grow the economy, create peace and provide human advancement, jobs and electricity. By closing your eyes when you face a problem it didn't go away, you just pretended it did. Similarly, these military rules have destroyed Pakistan, where no one could really set long term growth and stability goals. This is the first time long term planning is happening do I hope the system keep moving forward for a better Pakistan.
When ZAB got the seat it was full of feathers what did he add to it? Did Military at that time stop him from proper utilisation of those resources and sensible thinking? With all that public support what did he contribute?
2) The Civlian government isn't sitting on their couches eating Fish and Chips. They are running around, trying to fix the electric issue, deal with terrorism, violence internally by IK, issues in Karachi, Fata, Baluchistan, no power, no jobs, etc, etc. Its silly to expect quick decisions on such critical topic. Peshawer incident provided that unity that was needed. The military is like a hammer. When all you have is a hemmer, everything looks like a nail to you. You can't just quick deploy military, there is a lot of political will and work to provide support to the military.
When you are faced with lots of problems you prioritize those and assign a ranking like most critical, critical and least critical, then you look at your resources, allocate those resources according to your ranking of the issues. You set your development priorities right, plan for the most urgent projects on top priority, look for venues that will add to your scarce resources, BUT YOU NEVER START BUILDING USELESS FOOLISH METROS when you know your energy sector needs a push, you need new dams, you need to revive your industry. You go for long term sustaining projects that will result in resources to allow you build Metros and railways later on.
