JLA #78 (1997)

In stores February 26. With the new line-up in place, the Justice League intercepts a malevolent alien signal that threatens a nearby planetary system. Now the JLA must make the gut-wrenching decision: to maintain neutrality in a galactic conflict or to interfere in foreign politics by conducting a preemptive strike of its own. Either way, the consequences just might be cosmos-shattering!
