Why do Sudan’s humanitarian truces keep failing and who is to blame?

• Efforts to bring about truces in Sudan are continuing to hit a dead end, with fighting continuing and worsening the country’s dire humanitarian situation.
• Renewed efforts, including by the United States, to implement temporary truces to allow desperately needed aid into the country have repeatedly failed.
• Fighting has intensified in recent months, with the United Nations warning that the humanitarian system in Sudan is on the brink of collapse.
