When we are not fighting each other, we are helping each other out:

Israel has accused the Indian troops part of the UN peacekeepers along its border with Lebanon of doing nothing to prevent the infiltration of Hezbollah supporters into its territory, but on the contrary cooperated with them, a media report said.

This follows on similar allegations raised by the Israelis in 2006:

This is not the first time when Tel Aviv has accused Indian troops stationed in south Lebanon of having helped Hezbollah. Indian troops were blamed by Tel Aviv for not only quietly watching the abduction of three Israeli soldiers by Hezbollah in October 2000 but even assisting them after having accepted bribes.

Despite such grave allegations, Israel seems to be content with supplying India with over US$1 billion of military equipment a year. That kind of news really waters down such allegations.
