I fully agree. It is a mistake to conflate that basic/core principles such as one country not invading another country as a "western" value when these are universal. But the degree of response of individual members will be shaped by a combination of the local geopolitical expediency + cultural bias/affinity.
So a country might agreed that the invasion of Ukraine is wrong (basic principle), the response to it will be different.
For Eastern European countries, they see it as existential and hence are willing to give significant military, and financial aid in response. Another country, and we don't have to look too far, just Greece/Turkey, can be on the same page on the issue of invasion with Eastern European countries/and the rest of the EU, but they clearly don't see it in existential terms. And being different isn't wrong.
