TEL AVIV, Israel - Unilateral Israeli military attacks are not unexpected in this part of the world, as the wars with Gaza in 2008 and Lebanon in 2006 show.
In the past, Israel, with help from the United States, could rely on the acquiescence of the Egyptian government to do nothing. This week's attacks, the first large-scale Israeli operation since Arab Spring revolts erupted and toppled governments throughout the region, will seriously test whether the United States and Israel can still depend on Egypt's new government to hold the line.
