In his 2018 annual letter to shareholders, BlackRock CEO Larry Fink wrote that other CEOs should be aware of their impact on society. Anti-war organizations objected to Fink's statement,[118] saying that BlackRock is the largest investor in weapon manufacturers through its iShares U.S. Aerospace and Defense ETF.[119] In May 2018, anti-war organizations held a demonstration outside the annual BlackRock shareholders' meeting in Manhattan, New York.[120]
