The two words are NOT synonyms. Both Ha'Aretz AND the law have to learn to differentiate between the two. "Migrants", particularly economic migrants, are not refugees, they are people who move about, following the "money trail", chasing after employment not available in their home countries. Every state in the world has the right to refuse to accept migrants. "Refugees" are a different case entirely, and a separation between the two cases needs to be enshrined in any "Infiltration Law". I dare Ha'Aretz to post this.
