The world is a more dangerous place because of the global economic meltdown, according to Northrop Grumman Chief Executive Ronald Sugar, whose company provides specialized aircraft, radar and other electronics to meet that threat.

Sugar was the kick-off speaker at the annual Reuters Aerospace and Defense Summit on Monday in Washington, D.C.

Sugar acknowledged that hunger and thirst could not be solved with his company’s products but  argued that diplomats dealing with the world’s woes would be more likely to be successful if diplomats followed President Teddy Roosevelt’s famous dictum.

“You only talk if you have a big stick,” he said.

The Aero and Defense Summit is the final one of the year. In 2008, Reuters has had 33 summits around the globe and have as many or more planned for 2009. Our previous gathering, Reuters Investment Outlook Summit, provided clients with an excellent look at how to manage through what will certainly be a challenging 2009.
