Lior, about the same as getting married, apparently.
OK, here’s my version:
When our Yeshiva Bochur reaches the age of 21*
WE MIGHT OR MIGHT NOT SEND HIM TO YESHIVA IN ERETZ YISROEL
We will make our decision (with his input) based on the following reasons:
A) WE WILL NOT BE GUILTY OF GIVING BAD ADVICE TO HIM BECAUSE IT MIGHT BENEFIT SOMEONE ELSE. HE IS AN INDIVIDUAL, AND WE WILK TREAT HIM AS SUCH.
B) The 50 rabbanim who signed the kol koreh might be right that it’s a good idea in general, but they didn’t specifically address our son, who they never met.
C) He might need more time to learn without the ol haparnassah. He might OTOH need to be married to best benefit his ruchniyus. We will try to make whatever decision is best for him.
D) He might be mature enough to get married. He also might not, yet would benefit from a yeshiva E.Y.
E) He might or might not be the type of boy who is in danger of falling to the nisyonos of being 6,000 miles away. We will take this into consideration. (If he is, is he ready to get married?)
* and 17, and 18, and 19, and 20, and 22, etc.
