NATO Secretary-General Mark Rutte has called on member nations to present plans for meeting defense spending targets. This demand was made ahead of the organization's annual summit in Ankara, which is set to begin on Tuesday.

The summit comes at a critical time, as the United States reduces its security presence in Europe. Member nations had previously agreed to allocate a certain percentage of their gross domestic product to defense.

Further details on the summit and NATO's defense spending goals are available from the source. The organization's 32 member nations, including the United States, will be discussing these issues in the coming days.
