What was the US Defense Secretary's stance on potential cross-border operations into Mexico to combat drug cartels?

During a visit to the southwestern border, the US Defense Secretary did not rule out conducting cross-border raids to pursue cartels inside Mexico. When speaking to reporters, he specifically stated that 'all options are on the table.' This statement suggests an increasingly aggressive approach to combating drug cartels and fentanyl trafficking across the US-Mexico border. The vague yet significant declaration indicates the US government's willingness to consider military actions inside Mexico as part of its broader strategy to dismantle cartel operations and address the fentanyl crisis.
