The leaked cable to the US State Department from US Ambassador to Sri Lanka Patricia Butenis has this week added to growing calls for international investigations into the Rajapakse administration’s culpability for war crimes.

“Any mention of my island home (no matter what British political scandal it may involve), is most welcome. For here is a chance for the world to stop its hurried turning, pause a moment, and remember that savage kingdom in the Indian Ocean. To read once more of the 100,000 Tamils thought to have died in a few balmy days last May.

“Memory, that dignified defender of all human life, will not simply disappear. It is the archaeological remains of our collective existence. Those who bear witness can never forget until closure is achieved.”

“Japan's studied refusal to add to the international pressure on the Sri Lankan government, while it continues to pour money into infrastructure development, could be construed as not simply more ineffectual checkbook diplomacy, but in fact a cynical investment in the regime.

“Most of [Sri Lanka’s] deficit reduction plans hinge on turning around loss-making state ventures hampered by subsidy schemes, mismanagement and an infamously intractable corps of bureaucrats.”

Public sector resistance to the government’s proposed economic reforms, and poor government follow-through, “could put the [proposed] changes at risk, and leave potential foreign investors still wary of Sri Lanka as a destination," Reuters reports.

It isn’t surprising that the only British politician who will be meeting Sri Lanka's President Mahinda Rajapakse during his controversial visit to the UK this week is Defence Secretary

Amid a storm of outrage and calls this week by Amnesty International for Britain to pursue war crimes prosecutions against Sri Lankan leaders, the Defence Secretary is going to meet President Rajapakse “in a private capacity”.

"This reflects Dr Fox's longstanding interest in Sri Lanka and his interest in, and commitment to peace and reconciliation there," a spokesman for Fox told The Guardian newspaper.

A closer look at Dr. Fox's long-standing engagement with Sri Lanka suggests otherwise.

“There are no examples we know of a regime undertaking wholesale investigations of its own troops or senior officials for war crimes while that regime or government remained in power. In Sri Lanka this is further complicated by the fact that responsibility for many of the alleged crimes rests with the country's senior civilian and military leadership, including President Rajapaksa and his brothers and opposition candidate General Fonseka.”

“The Oxford Union has in the past faced criticism for inviting other controversial speakers also known for their racist views. However, President Rajapakse is in a different position from [far right leader] Nick Griffin or [Holocaust denier] David Irving.

“These previous speakers live in countries with a free and independent media and the rule of law. They could not therefore use the Oxford Union as a means of propagating unchallenged, noxious views or indeed as a platform for a campaign of concealment.

“Would Sri Lanka be better off wagering on the intelligence of President Rajapakse and his relatively small circle, or on the creativity and hard work of a broader entrepreneurial class? The fact that foreign direct investment, and domestic long-term investment money, is sitting on its hands a year and a half after the war is a sign of which side of that bet the market is taking.”
