It’s important to understand what Hamas stands for.
Hamas defines itself as being in a continuous state of war with Israel. The group refuses to recognize Israel’s right to exist. Hamas’ charter states:
“Israel will exist and will continue to exist until Islam will obliterate it, just as it obliterated others before it.”
Hamas’ so-called spiritual leaders provide religious justification for unimaginable depravity. In their sermons, they consistently incite their followers to hate Israel and Jews.
“…our mantle is ‘Death to the Jews and to America.’”
