Trump’s Mineral Deals Could Bring Peace in Congo

"Your election has ushered in the golden age for America," wrote a supplicant trying to curry favor with President Donald J. Trump last month. The letter, which was reported by the Wall Street Journal on Wednesday, did not come from a sycophantic follower, a would-be political appointee, or someone seeking a pardon. It came from Félix Tshisekedi, the embattled president of the Democratic Republic of Congo, who is facing down a domestic rebellion supported by neighboring Rwanda.
