US military forces have not destroyed a suspected drug boat in a month, marking the longest pause in attacks to date. The pause has raised questions about the effectiveness of the campaign. US law enforcement officials have expressed uncertainty about the lasting impact of the attacks after 11 months.

Experts are also skeptical that the attacks will significantly change the drug trade in the region. Further details about the US military's efforts to combat drug trafficking are available from CNN, including information about the number of boats destroyed and lives lost. The official mission of the operation, known as Operation Southern Spear, remains classified.
