"Under the new regime of US President Donald Trump, India is getting more weight than Pakistan. Earlier, both the countries were treated equally, but now the situation has changed," he said.
Pressler was speaking here at the launch of his new book -- "Neighbours in Arms: An American Senator's Quest for Disarmament in a Nuclear Sub-Continent".
During his speech, he dwelt on a wide range of issues, including Indo-Pak relations, China, growing tension among countries holding nuclear weapons and lobbying that is influencing the foreign policy of countries, including the US.
On the Indo-Pak relations, he said, "Pakistan was a pet state of generals in the Pentagon, more so of the arms lobby and more so of the octopus, hence was the equal treatment to India and Pakistan, despite India's reservations. We do need generals, but they needed to be controlled by the Congress."

Commenting on the US foreign policy, he said, "We had almost lost control over our foreign policy. The law firms had at least a law of not having clients from both the sides, but the newly-emerged consultancy firms...they do not have such a binding."
