For the last six years, Mexico bragged about its oft-questioned “hugs, not bullets” strategy, in which its leaders avoided confrontations with drug cartels that were gradually taking control of large parts of the country. The thinking was that social programs, not shootouts, would gradually drain the pool of cartel gunmen. Now, a month into the term of new President Claudia Sheinbaum, a string of bloody confrontations suggests the government is quietly abandoning the “no bullets” part of that strategy and is much more willing to use the full force of the military and the militarized National Guard.
