The double standards of US policies are crystal clear. On the one hand, USA clamours for Georgia's territorial integrity and sovereignty but continues to violate Pakistan's territorial sovereignty blatantly. America favours democracy but opposes it if it brings Islamists into power. Nuclear non-proliferation is supported in case of Iran but a carte blanche is provided to Israel and India. America deems free trade to be the elixir of economic growth but supports subsidies when it comes to agriculture of the rich world. Due to these duplicitous policies, America's moral credibility is constantly eroding all across the world. -RIZWAN ASGHAR CHAUDHRY, Lahore, via e-mail, September 20.
