Regarding the current conflict in Gaza, two points ought to unite world opinion:
First, it's a war crime for any governing body to launch rocket attacks on civilian targets in neighboring countries.
Second, it's appropriate for any nation hit repeatedly by such attacks to move promptly to eliminate those rockets.
In this context, the silence from the UN is particularly appalling. The Hamas terror state in Gaza couldn't exist for a week without hundreds of millions in aid support from the United Nations Relief and Works Agency for Palestine, which spends a total of $1.2 billion a year.
The U.S., which provides by far the biggest share of that budget—must insist that the UN end all such assistance until Hamas stops all rocket attacks. Israel has already pledged to halt air strikes whenever missiles from Gaza stop, a halt that the world must unite to demand.
