All,
      Whatever the guy in the poster has outlined is very possible. Because of three very simple reasons.

1) Nepal is not the very very poor country it used to be in the 1980s. Nepal may lack infrastructure but there are enough Nepalis with with the resources and money who can help build the country. The NRN movement is also doing a lot of social/development work and will only increase.

2) Nepal's goverment is not poor these days. It collects about 300 billion a year in taxes and gets another 150-200 in aid. Thats 500 billion.

3) Lastly, the goals in the poster above are not that impossible to achieve. Any country worth its salt produces enough electricity, has highways , railroads and couple of international airports. They're not talking about building a space program, its just about some basic infrastructure that more than a 100+ countries already have. And NO, the completion of the above projects wont turn Nepal into Switzerland or Singapore, may be more like Vietnam or Philippines.

4) Some of the above projects have already began, moving as scheduled or neared completion

-Sikta
-Babai
-Upper Tamakoshi
-Mid Hill Highway
-Upper Karnali
-West Seti
-Kathmandu Tarai Fast Track
-Melamchi
-Pokhara Airport

All of the above projects are scheduled to be over in the next 2-7 years, so even with a little delay 10 years definitely sounds reasonable.

Thanks.
