Can I suggest that people log in to YouTube, visit the IDF webpage, and flag their videos as inappropriate.

You can flag videos as being inappropriate because they encourage hatred or violence towards ethnic groups.

Let YouTube know that these videos are not 'general interest' but hateful military propaganda.

PS, if you look at the statistics on the IDF videos, there is no way that 'not enough people are logging in'. Many of them are in the top #10 videos viewed in the month.
