Is this sentence correct?

Let me say that I harbor no resentment over the actions of Israel's leaders. For more than 60 years, they have knowingly made their country a pariah in the Arab and Islamic worlds, just as the Palestinians have made themselves pariahs in much of the West. This is, of course, the right of both parties, but neither seems to want to face the consequences of their decisions. With demographic realities and increasingly radical, well-armed Arabs making them panicky about Israel's security, Israel's leaders naturally to try to lock down as much U.S. support as possible. Having consciously – if unwisely – put all their eggs in the U.S. basket since the 1973 War, Israel's leaders must do everything possible to protect their relationship with Washington.

I don't understand the sentence I put on italic because the words I put in bold seems to be improper here.
