Pakistan is a political mess, and with that come the dangers that make it arguably one of the most dangerous countries you could go. You would be much safer with Grizzly Bears here in Greater Yellowstone or Chupacabras farther south.
So in short an absolute no.
I know the peaks are higher and the culture is different, but why would you do that befoer any of the multitude of incredible backpacking here in the States. You could do the Colorado Trail, CDT through the Winds. The JMT.
Well, wherever you end up going I wish you the safest of trails.
