Pakistan was blamed for an attack on an Indian military base last week, which ramped up already high tensions — especially in the disputed region of Kashmir, where there's technically a cease-fire.
Still, Pakistan didn't seem convinced that India wouldn't use its armed forces. On Tuesday, Pakistan's military said it was ready for a strike.
If Pakistan does hit back, tensions could bubble over in the region and possibly pull in the international community.
But two world powers that could get drawn in — China and the U.S. — seem to be distancing themselves from the conflict even though both have strong ties in the region.
