Bruton's comment comes on the heels of President Obama's announcement Friday morning that he is sending 4,000 more U.S. troops into Afghanistan on top of the 17,000 additional forces he has already announced he is deploying.
It also comes amid reports that an Afghan National Army soldier today killed two NATO troops and then himself.
"There may be some additional troops for some purposes," Bruton said. "Particularly training was mentioned by President Obama [in his speech this morning], and I've no doubt that we would be willing to provide training for the Afghan army and the Afghan police. The development of the Afghan police is very, very important."
Bruton also discussed the differences between the Obama administration and that of Mr. Obama's predecessor, George W. Bush.
"Well, I think there's a willingness to confront unpleasant facts that's notable in this administration," he said. "I was particularly heartened, for example, by what Secretary of State Clinton had to say in the last two days about the extent to which consumption of drugs by Americans – and she could have said Europeans, as well – is contributing to the problems of law and order in Mexico."
