"If that is what they choose, then we shall win a settlement on the battlefield."

"Hard choices are going to have to be made in the next few days."

"The Communists have made it clear that up to now, thus far, they are unwilling to negotiate or to work out a settlement except on the battlefield."

"The people of America, Mr. Prime Minister, are delighted to have this opportunity to return your friendship."
