Do it now, and then you will realize how silly this statement of yours is: "If an arab individual refuses to accept the sovereignty of the Israeli government over State territory, will he/she be allowed to return anyway?" The answer is NO. Expicitely set out in 194; NO. He is not allowed to return. But he also can not be fobbed off; he must be compensated by the State of Israel. The same answer to all your other questions; if he does not agree to live as a good, upstanding, peaceloving Israeli citizen then he can not return, but Israel can not simply say "on your bike, sonny". Israel must compensate him. Israel can deny entry to ANY of the refugees, or to ALL of the refugees, or to NONE of the refugees - the choice is Israel's alone. But each refugee denied return must be compensated for their loss, regardless of the reasons WHY that refugee is denied (or refuses) the Right of Return. That is what 194 says, RAB.
