Ethiopia’s PM Abiy Ahmed -- who won last year’s Nobel Peace Prize -- has ordered a military offensive on the northern Tigray region of the country. Ahmed, who won it for ending the 20-year conflict with Eritrea, is far from the first laureate to later wage or support war.

Barack Obama: The first black US president got the prize only nine months after his inauguration in 2009. But far from ending America’s foreign wars, as he said he hoped to do, they continued for all eight years of his term, with airstrikes or military operations in Afghanistan, Iraq, Syria, Libya, Yemen, Somalia and Pakistan.

Aung San Suu Kyi: The reputation of Myanmar’s leader has been left in tatters with the country accused of the ethnic cleansing of Rohingyas and trampling on the rights of other minorities. The 1991 laureate, who won the prize for her heroic resistance to the country’s military, now rules in an uneasy power-sharing agreement with them.

Henry Kissinger: In 1973, the US secretary of state shared the prize with North Vietnam’s Le Duc Tho for negotiating ceasefires that didn’t hold. Critics said the award “made political satire obsolete” given Kissinger’s role in the carpet bombing of Cambodia and Operation Condor killings to keep pro-US South American dictators in power.

Theodore Roosevelt: The then US president won in 1906 for negotiating an end to the Russo-Japanese war a year earlier. But even at the time, the nomination of the “military mad” leader of the “Rough Riders” volunteer cavalry regiment in the Spanish-American war, was disputed, with Swedish newspapers saying Alfred Nobel would be spinning in his grave.
