Surprised yes is so high. Even in ideal circumstances EU application process is grueling, slow and with a bunch roadblocks (any existing EU country can block/veto it for any reason). Example: For Croatia it took 13 years and it was blocked all the time by the neighbours and that was in much better time for EU enlargement.

I understand there is a lot of public support for Ukraine given the situation but Its hard to see that will still hold once conflict is resolved. There are also other factors, EUs general decline and economic issues, increasing political polarisation...its just hard to see EU having capacity to accept a big country like Ukraine with huge problems with economy, security, corruption.. in such a short timespan.
