Delta Green isn't just for the present. Its origins as P Division trace back to the Project Covenant raid of Innsmouth in 1927, through World War II and the official years, even through the horrors of Cambodia in the Vietnam War. The original books were set in the 1990s, but Delta Green is a game of the present day, a moving target; see Delta Green after 9/11. A campaign can also stretch long into the future. The enemy is always there, even to the Endtimes, though we are not.
