According to a March 25 NYT opinion piece:
Few in the protective equipment industry are surprised by the shortages, because they’ve been predicted for years. In 2005, the George W. Bush administration called for the coordination of domestic production and stockpiling of protective gear in preparation for pandemic influenza. In 2006, Congress approved funds to add protective gear to a national strategic stockpile — among other things, the stockpile collected 52 million surgical face masks and 104 million N95 respirator masks.
But about 100 million masks in the stockpile were deployed in 2009 in the fight against the H1N1 flu pandemic, and the government never bothered to replace them. This month, Alex Azar, secretary of health and human services, testified that there are only about 40 million masks in the stockpile — around 1 percent of the projected national need.
Assuming that info is correct (if not feel free to post a frame-challenge answer), why did the US not replenish its national strategic stockpile of masks after the 2009 pandemic? (E.g., would that have required the introduction of new legislation? Was such legislation introduced but defeated? Or was it not just introduced for some stated reason(s)?)
