There are many different levels of commitment.
I really don't want to question either this girl's rationale or level of commitment, but when a young girl from Washington State, heads into a region torn apart by war, she has to be willing to accept the risk, irrespective which side she chose to take.
Perhaps she felt personally her sacrifice was worth the risk, we don't know because now all we hear is others speaking in her memory, on her behalf.
It seems her parents now feel the cause was not worth the sacrifice. I don't know if they tried to discourage her from going. If they did, maybe they should have tried harder.
If they had, maybe now they wouldn't have to be asking the U.S. government to do "something more" in her behalf. Besides, its really too late anyway to do any good for Rachel.
Instead of blaming the Israelis and the U.S. government, I think Rachel's parents could better spend their time assessing whose fault is it really that their 22-Y-O daughter is dead.
Instead, it appears her parents, and this writer, are blaming everybody but Rachel herself.
"Perhaps she felt personally her sacrifice was worth the risk..."
Should read: Perhaps she felt her cause was worth the risk, and ultimately her sacrifice...
