Advertising is largely a cargo cult, with the "advertising/marketing is the most important thing" mindset being pushed by people with a vested interest in getting you to spend money on advertising. Actual, real businesses buying actual, real advertisements have said they saw basically no difference in revenue before and after buying the ad.
Don't get me wrong, it's not like there's no point in advertising--small businesses need it to jumpstart their client base, and medium/large businesses use it to make sure their products maintain mindshare so that a customer is more likely to think "I want a Coke" instead of "I want a soda." But in terms of directly influencing customer purchasing decisions, the biggest influence is old-fashioned word of mouth and direct customer experience, not advertising.
The reason I know I'd fail as a politician is because the instant I get asked anything about Israel / Palestine, I'd either run away screaming or I'd throw my hands up and say "I'm not touching this with a ten foot pole, they both suck and everyone except the civilians caught in the crossfire deserve whatever they get."
This whole conflict isn't black and white morality, or even black and gray morality. It barely qualifies as black and slightly-less-black-if-you-squint morality. It's like Luke trying to blow up the Death Star, if the Death Star was populated mostly with families, children, and puppies, and Luke ate a baby while he was rescuing the princess.
