Defense Secretary Chuck Hagel was in Afghanistan this weekend.
It's his first trip in his new role as Secretary.
The Vietnam War vet says he traveled to the war-torn nation to thank troops for their service.
He spent time with soldiers in Kabul Sunday ....shaking hands and chatting.
Hagel also says he wants to get a better understanding of the current situation in Afghanistan.
Meantime, a joint press conference with Hagel and Afghan President Hamid Karzai Sunday was canceled.
The cancellation followed comments from Karzai on a deadly Taliban suicide bombing Sunday in Kabul during Hagel's visit.
Karzai says the blast shows the "Taliban are serving the foreigners and are not against the foreigner."
He also says it's a sign the militant group wants "foreigners" to stay.
