Success is not assured, but America is resolute: this is the best chance for peace we are likely to see for some years to come - and we are acting to help Israelis and Palestinians seize this chance.

Rice frames U.S. diplomacy as a mix of realism and determination: peace is uncertain (“not assured”), yet the United States intends to press forward (“America is resolute”). By calling it “the best chance…for some years,” she implies a narrow window created by contingent political conditions—leadership, regional dynamics, and international attention—that may soon close. The line also positions Washington as an active broker, not merely an observer, emphasizing facilitation (“help…seize this chance”) rather than imposing an outcome. Rhetorically, the quote balances caution with urgency, aiming to justify intensified U.S. engagement while managing expectations about results.
