According to research Vanga's prophecies are about eighty percent accurate." She was blessed with supernatural abilities for accurate psychic predictions of the future. Here are some predictions she made:

Vanga predicted the 9/11 terrorist attacks in the United States, when she said that American brothers would fall under attacks of birds of steel. Vanga prophesied the perestroika in the USSR, the death of Princess Diana and thousands of happenings in people's personal life.

She became very popular in Russia since her prophesy about Kursk became true. Vanga prophesied the sinking of the Kursk submarine, "At the turn of the century, in August of 1999 or 2000, Kursk will be covered with water, and the whole world will be weeping over it." (1980) And in August 2000 the kursk submarine sank in an accident everyone on board died.
“Black President election will destroy USA”

Baba Vanga prophesied even that the 44th US president would be black and he would be “the last one.” She went on, saying that at the time of his stepping into office, there would be a spectacular economic crisis. Everyone will put their hopes in him to end it, but the opposite will happen; he will bring the country down and conflicts between north and south states will escalate. Many articles were written about that:

“Vanga predicted a black man to become the 44th U.S. President (after George Bush), and this President will be the last one because America will freeze up or go down in the economics. It probably can divide into the North and South states,” DobryachOk writes.

“Vanga’s prediction sounds like this: when a black President is elected problems come to the U.S.,” an anonymous author says.

“Vanga predicted African American President could lead the U.S. to a miracle and the whole world would win,” nusha states.

“Vanga predicted America would have the crisis and here you are!”

Vanga mentioned the possibility for the situation to escalate to a third world war in which the nuclear bomb would be used again.
