The Hamas attacks were barbaric and horrific. Israel giving 1 million+ people 24 hours to leave or risk being destroyed in a bombing campaign while cutting off access to food, water, and fuel is barbaric and horrific. There is such thing as nuance, but it doesn’t take very much critical thinking to recognize that both Israel and Hamas are commiting atrocities.
This is one of the most commonly touted engineering myths that simply doesn’t hold up to even a brief analysis. The first glaring problem is the inherent survivorship bias behind claiming Roman concrete was objectively better than modern concrete. As other users have already mentioned, modern concrete is actually very strong and exceeds the strength of Roman concrete when such strength is required, but where it really has an advantage is in its consistency.
If every concrete structure built in Rome was still standing and in good shape to this day, engineers would be salivating over the special blend and would be doing whatever they could to get their hands on it or replicate it. But we don’t see that. We see the Roman concrete structures that have survived the test of time (so far), not the myriad structures that have not. Today’s concrete on the contrary is deliberately consistent in chemistry, meaning even if it typically isn’t designed to last hundreds of years, you can say with a great deal of confidence that it will last at least X years, and all of it will likely exhibit similar wear and strength degradation behaviors over that same duration.
There are other factors at play too:
None of this is to detract from Roman ingenuity, but to make the claim that Roman concrete was objectively better than what we have today is farcical.
Sure. Except “letting them evacuate” in this case is better characterized as “continuing to expel them from their homes under threat of violence.” I’m not arguing the 24 hour time period is the atrocity, I’m arguing the act of creating a humanitarian crisis under the auspices of a military campaign effort is abhorrent.
It’s not like we don’t have any good reporting on the matter either. The BBC for example has already been attacked because they refused to declare Hamas as terrorists (a label I agree with, for the record).
