none of the countries have killed as many children as Israel

Number of killed civilians by Russian forces: 6861 - 8729+

Add a couple hundred of killed Georgian civilians and you have a range for Russian civilian kills in the last 30 years of:

80,000 - 230,000

If we count genocides perpetrated by Turkish nationalists in the Ottoman Empire and continued by newly founded Turkey we have:

• 600,000 - 1.5 million Armenian civilians killed
• 300,000 - 900,000 Greek civilians killed

As to genocides perpetrated solely by the state of Turkey:

Turkish Kurdish anthropologist Dilşa Deniz estimates the number of deaths to be between 46.000 to 63.000.[65][66][67][68][69][70][71][72] Historian Hans-Lukas Kieser writes that 40,000 is implausibly high.[73] Historian Annika Törne estimates 32,000 to 70,000 dead as a result of massacres

Deaths: 5,000 - 15,000

Several hundred more Kurdish civilians have been killed in the past few decades by Turkey.

But you’re right that in the past few decades Turkey hasn’t killed as many Kurdish civilians as Israel has Palestinian civilians. Turkey is “just” commiting cultural genocide right now.
