The Bernie Sanders campaign isn’t alone among events in the United States capable of inspiring international solidarity. On February 15 and 16, 2003, nearly a million antiwar protesters marched against Bush’s invasion of Iraq. On May 1, 2006, more than 3 million predominantly Latino workers effectively called the largest one-day strike in the nation’s history to demand immigration reform. In 2011, the Occupy Wall Street movement found common cause with the Indignados in Spain, while Egyptian revolutionaries in Tahrir Square ordered pizza for workers and students sitting in at the Madison Capitol building. And in 2014, Palestinian activists offered advice to Ferguson, Missouri, protesters about how to best withstand the effects of tear gas.
