ISLAMABAD - A renowned US scholar, Robert Jenson, criticizing the US unilateral foreign policy Friday said that Pakistan must no more trust over USA. "The US Empire is on the decline and the indicators often used to describe all-encompassing change include new unilateralism, militarisation and attack on constitutional rights are not new to US imperialism." He was expressing his views while addressing a public talk titled, "The Multiple Crises of Empire", held here on other day at Institute of Strategic Studies Islamabad (ISSI). Former Ambassador Khaild Mehmood commenced the public talk with a brief overview of the topic under discussion. "Attack on constitutional rights can also be traced back in history. Keeping in view the historical record of the US, nothing unique has been introduced in the post-9/11 era: the policies of Bush administration might be different in degree but are not different in kind", Jenson claimed. Robert Jenson, in his address, focused on two themes. Firstly, challenging the general perception that everything has changed in America in post-9/11 scenario, he said that on ground nothing has actually changed. Secondly, he criticized the spiritual values existing within America. He said that going back to 9/11, the only major change that occurred was the creation of a new ideological space in which US was accepted as an empire. The Americans had been denying the imperialism of their country, but after 9/11 they became more honest and accepted the reality. Talking about the spiritual values in US, Jenson said that he is not here to talk about apocalypse but he believes in end of world in terms of dissipation of energy sources.  There are illusions that technology would solve climate crisis, but it would not. "We should realize that era of industrialization and mass consumption is over because of the dissipation of energy resources but Americans do not realize this because they lack critical thinking", he stressed. He observed that Americans do not distinguish between market & state and the affluence and consumption are affecting spirituality of American citizens", he added. At the end he said that Pakistan could learn a lot form US.  Concept like freedom of expression is indeed worth learning. He said that what he wants Pakistanis to learn from US is to avoid the mistakes, which Americans have made. US have an irrational nationalism. It believes in imposing its political, economic and religious ideas on others, he added. Pakistanis need to be wary of such irrational approach. They also need to avoid the spiritual crisis, which Americans are suffering from. They should address the spiritual question on their own accord and find a way to know what it means to be a human being. They should base their concept of humanity on justice and sustainability. Jenson warned that if we don't address this spiritual question of human identity we have begun to leave this planet as species. Dr. Justin, another speaker, began by identifying the numerous dimensions of an empire, and technically defined an empire on the basic level as an entity that controls the politics, economics, and foreign policies of another country from the outside and he claimed that a country is the subject of an empire if the policies are being determined by external forces. The Director General of the Institute, Dr Tanveer Ahmad Khan marked the end of the session with a brief analysis of the issue, and thanked the speakers for their stimulating presentations.
