HELSINKI (AP) — Ex-NATO chief Anders Fogh Rasmussen is opening a consultancy in Denmark to give strategic advice to governments, organizations and corporations.

The 61-year-old former Danish prime minister, whose five-year term as the alliance’s secretary general ended Sept. 30, says the Rasmussen Global agency aims to facilitate “deep strategic thinking.”

Announcing the launch of his consultancy on its website on Wednesday, he said that after “five hectic years” at the alliance he wanted to help clients “navigate in an increasingly complex world … (where) the balance of power is changing.”

During his NATO tenure, the alliance continued to wage the longest and most expensive military operation in its 65-year history in Afghanistan.

Fogh Rasmussen is succeeded by former Norwegian Prime Minister Jens Stoltenberg.
