Remind me Foxsake where Jewish children or in fact any children in Europe were "allowed to be evacuated" to in WW2? The only children who were evacuated were English ones to the countryside in WW2 and the 2 kindertransport of just under 10,000 Jewish children from Austria and Germany before WW2. Once war broke out it stopped and children were the first to be killed.
Now look at what happens in Israel. While Gaza is "under blockade" children are not only allowed to receive treatment in Israeli hospitals which are of a higher standard but are even funded by foundations in Israel en.wikipedia.org/wiki/Health_care_in_Israel. Furthermore since the conflict has started 124 truckloads of supplies - including medical supplies, food, and gas - were delivered from Israel to Gaza. That's while Gaza was sending 880 rockets and had killed 5 Israelis. Quite a blockade.
Before starting sending rockets to Gaza, the IDF dropped flyers in Arabic throughout Gaza broadcasting what they were going to do and telling everyone to avoid being present in the vicinity of Hamas operatives and facilities of other terrorist organisations that pose a risk to your safety. That's rather more warning than Hamas give Israeli women and children. They get a siren at any time of day or night. Israeli babies have nowhere to go other than their shelters providing they get there in time (less than 20 seconds) and don't receive a direct hit. I hear your concern for all children loudly and clearly in your post.
In addition, it is very difficult for Gazan women and children to avoid being used in this conflict because that is the exact aim of Hamas. They want to kill their own women and children to prove how awful Israel is. these are the words of Hamas.
This is not genocide or even close to it. Your comments are shameful. The awful lesson that can be learnt from the Holocaust is that unless you have political and military support and independence people will happily sit by and watch you die. Look at the Armenians, the Rwandans, Sudan and more. Only the Palestinians seem to raise such levels of sympathy. How very strange.
