you can, however, orbit 2 or 3 molynia orbit satellites that accomplish effectively the same concept of persistent coverage over a certain geographic area. The orbit would be calculated to put the long dwell time of the apogee of the molynia orbit of each satellite over the target area.

this is far more useful for anything that is sigint/communications based, or space based radar, than anything as a weapon.

Although not to the same level of accuracy as "hovering" over a specific longitude along the equator as in geostationary.
