It feels more likely that if you push the message "yes, this is great" for the short term win they get elected again next term.
When do you switch from saying "yes these people are great for flip-flopping" to "no these people are terrible don't vote for them", and how do you say it in a way that gets through people's subtlety filters and doesn't make it look like you're flip flopping yourself?
If we want to use Gaza as a political tool to achieve some political aim (ie get my guy elected), that will be in conflict with doing something to help Gaza. Because in most countries, doing something meaningful is likely going to require cooperation between politicians from different parties. And it’s hard to get people to cooperate if you don’t plan on sharing the credit.
I do think cooperation and letting bygones be bygones for the sake of progress are important.
But I don't think it's right to frame it as "get my guy elected" vs "help Gaza". Does decrying them on social media mean they will flip flop again and be pro-gaza massacre? Even if that's the case, it's "get someone elected who will avoid Gaza-like tragedies in the future" vs "help Gaza now" which isn't black and white. Also, these people cooperated to enable the massacre in the first place...
