The argument that the US/West looked the other way in the case of Pakistan, during the East Pakistan crises or at any other time, is not completely accurate.
Pakistan was in fact under US sanctions from 1965 through 1975, despite ostensibly being a 'cold war ally'. The Western media did not fail to highlight the alleged atrocities by Pakistani forces in East Pakistan, and Pakistan came in for criticism from the US Congress and the West in general over HR abuses in EP. It was in fact a unilateral decision by Nixon to try and covertly support Pakistan, and given the rather short timeline of events from March 1971 to December 1971, and the lack of any independent and thorough analysis of events during the conflict, Nixon can't be blamed for not raising the issue.
The 65-71 period was because Pakistani generals indulged in an unauthorised use of weapons and a war. That did'nt stop Nixon nuding Iran to provide Fighter jets to Pakistan or sending an Aircraft carrier group to Bay of Bengal. And ofcourse the western media did highlight the situation in East Pakistan, but the same media highlighted and continues to highlight the situation in Kashmir as well. And just like individual Congressmen raised the East Pakistan issue, there were and are Congressmen who raised Kashmir and wanted to pass resolutions on demanding India to conduct a plebescite. The USG on the other hand refrained from raising the issue.
I have not seen any official govt. pronoucenments from the USG about Swat HR situation. All of them were media reports,"leaked" reports and so on. And it started mainly AFTER the mobile videos starting circulating. Otherwise it were mainly media reports and HR groupsEven in SWAT, the US administration, Congress and Western media in general highlighted the issue of extrajudicial killings several times, within weeks of the reports being made public. There was talk of ending military relations with Pakistan because of that alleged abuse, within weeks, to put pressure on Pakistan, again, despite Pakistan ostensibly being an 'indispensable ally in the WoT'.
Compare this to the situation with India, where a thorough investigation by the ICRC (and various other groups over the years) clearly establishes systematic atrocities by Indian security forces, conveyed it to the US, and the US just sat on it and said not a word. Even now that the information is public, there is largely silence in the West and from the US Congress and Administration. That is in stark contrast to how the West has dealt with Pakistan, whether Pakistan was an ally or not.
I think you might not be aware the situation in the 1990s. There were rabit anti-India tirades from the secretary of state. Bill Clinton use to mention the Kashmir issue in UN GA sessions and Congressmen were raising and proposing resolutions censuring Kashmir. Its only post 2001 that US has quieted down. Its just a matter of perception on how you take it. But if you go through news reports, UN sessions and western government pronoucenments they were quite virulent.
Afterall, after the fall of the soviet, Yugoslavia and India were the only USSR allies left. China was considered alright as it had started working with the USG. So Yugoslavia is no more and India was to be "managed" as well. Its just deft diplomacy that India managed to turn around the tables andget close to the US after 40 years of acrimonius relationship.
I am also not aware of any US plan to vote on any UNSC resolutions that would have sanctioned India for its HR abuses, and AFAIK, Iran allegedly blocked a vote on a resolution tabled in the OIC, not the UN.
The OIC supported and many western countries were passing a resolutiong on the UN Human Rights commision resolution condemning India on HR abuses. The resolution has to pass unanimously. All members were either OIC members or Wester governments. Iran was the lone no vote that blocked the resolution.
The resolution I am talking about was tabled at the UNCHR and once that passes, it goes on to the UN Security Council were punitive measures are passed. OIC ofcourse passes a number of resolutions but they dont actually matter.
