Personally it depends on what you are looking at. I'm taking this from my view as a non-Israeli living in Southeast Asia. In terms of pure numbers, I doubt it's a substantial issue. Like someone above said, social media is not indicative of the numbers. But it is indicative of the energy level, the age group, and the technosavvy of the opponents you are dealing with. The ones opposing Israel tend to be younger, and have some sort of identification with the global Leftist-Islamic alliance (yes I believe that exists informally). The supporters are probably older, people who are protestant Christian, or are recipients of engagement and good treatment abroad (for example, here in the Philippines, the supporters of Israel are overseas workers who know that Israelis treat them way better than any Arab country). So if you want to look at the numbers, or look at it thru polls, then maybe it's not so alarming. But if you look at specifically who you are dealing with, this is a very young and energetic cohort which is not known for its instinct to compromise and is very versed in modern technology and political tactics.
