The next morning, my grandfather’s staff lined up at the gangway to shake his hand and bid him an affectionate farewell. - John McCain

In the end, I am morally bound to speak only to the things that command my allegiance, and to which I have dedicated my life's work: the Republican Party, and more importantly, the United States of America. I will not refrain from doing my utmost by those lights simply because it may benefit others with whom I disagree. I claim no moral superiority over Donald Trump. I have a long and well-known public and private record for which I will have to answer at the Final Judgment, and I repose my hope in the promise of mercy and the moderation of age. I challenge the nominee to set the example for what our country can and should represent.

I’m sure there are legions of committed national security officials working hard to figure out how to combat his cyberattacks, his disinformation campaigns, and his possible, even likely, effort to hack into our voting machines. But President Trump seems to vary from refusing to believe what Putin is doing to just not caring about it. Just last November he appeared to take Putin’s denials at face value. “There’s nothing ‘America First,’ ” I pointed out, “about taking the word of a KGB colonel over that of the American intelligence community.” And some House Republicans investigating Russian interference seem more preoccupied with their own conspiracy theories than with a real conspiracy by a foreign enemy to defraud the United States. Unless the elected leaders of our government provide persistent direction and leadership and resources to officials working to defend our democracy, we won’t stop Putin’s next assault. With a nominal investment of resources, and a bold disregard for our resistance, Putin’s interference in our last election achieved all his objectives. He damaged Hillary Clinton’s campaign, but that wasn’t his most important priority. Encouraging our government’s dysfunction, and disaffection and distrust in the polity were his main objectives. He sees evidence of his success every day in our polarization and gridlock.

This is a far-reaching piece of legislation, but there is one challenge it could not address: the dangerous mismatch between growing worldwide threats and arbitrary limits on defense spending that are in current law. This mismatch has very real consequences for the thousands of Americans who serve in uniform and sacrifice on our behalf all around the Nation and the world. Our troops are doing everything we ask of them, but we must ask ourselves: Are we doing everything we can for them? The answer, I say with profound sadness, is we are not. Since 2011 the Budget Control Act has imposed arbitrary caps on defense spending. Over the last 5 years, as our military has struggled under the threat of sequestration, the world has only grown more complex and far more dangerous. Since 2011 we have seen Russian forces invade Ukraine, the emergence of the so-called Islamic State and its global campaign of terrorism, increased attempts by Iran to destabilize U.S. allies and partners in the Middle East, growing assertive behavior by China and the militarization of the South China Sea, numerous cyber attacks on U.S. industry and government agencies, and further testing by North Korea of nuclear technology and other advanced military capabilities. Indeed, the Director of National Intelligence, James Clapper, testified in February that over the course of his distinguished five-decade career, he could not recall "a more diverse array of challenges and crises" than our Nation confronts today.
