After long deliberations, the Israeli Post finally came up with a list of countries that we're not supposed to mail to. Not many surprises there, except for one: Algeria. I have already managed to send them postcards, with various degrees of success. So as usual, the guiding principle is "don't worry, it's gonna be fine".
Just by watching this lovely smiling face, you get the feeling that everything is gonna be just fine.
(By the way, I changed my Postcrossing settings to "send to repeated countries". I hope this eliminates problematic destinations, such as Latin America, Malaysia, New Zealand and such...)
