Apple Inc. Chief Executive Tim Cook has long advocated for changes in the U.S. tax code that would allow him to bring some of his company’s billions in overseas profits home, but in an interview published Thursday, he said that the benefits of a one-time tax break on that money would be felt much more widely than in Silicon Valley.

“ ‘That’s not the parochial view of what’s best for Apple. That’s a view of what’s good for America.’ ”

Cook also went into more detail in an interview with Bloomberg Businessweek on how he thinks the U.S. should handle a so-called repatriation holiday, which would offer a lower tax rate to push companies to bring back billions in cash currently held overseas. Interestingly, he would like the one-time tax to be forced on companies whether or not they bring the money back to the U.S., with a bill for “a reasonable percentage” issued on all profits held overseas.

President Trump spoke of a repatriation holiday during his campaign, targeting a one-time rate of 10%, much less than the top corporate tax rate of 35%. But Trump has not committed to whether the plan would be voluntary or forced. Trump has also suggested chopping the corporate tax rate in more than half, to 15%, as part of his plan for a tax overhaul.

Cook said he agreed that the corporate tax rate could be dramatically reduced, perhaps to that 15% number, but he would want to do away with all corporate deductions to make that happen.

“I think when you begin to open the door to things that people want, it doesn’t close,” Cook said of tax relief. “It just keeps opening and opening and opening.”

That statement is surely true for companies that hold their overseas profits offshore and hope the U.S. government eventually cuts them a break again. Companies were offered a 5.25% repatriation rate in 2004, and brought home more than $300 billion during that voluntary holiday, but a Senate investigation later found the program “failed” because the companies that took advantage still cut workforces and research spending in the aftermath, while spending the cash on executive pay and investor return.

Apple AAPL, +3.75% could push a fresh holiday’s returns toward $300 billion on its own. The tech giant reported $256.8 billion in cash and equivalents in May, and CFO Luca Maestri said at the time that 93% of that total was overseas. Apple has continued to let its cash pile build outside the U.S. while taking out loads of debt to ship profits back to shareholders in the form of dividends and share repurchases, helped by low interest rates.

Cook’s solution to a pattern of companies holding cash overseas until they receive a repatriation holiday is not doing away with the process of taxing overseas profits when they make it back to the U.S., but instead charging a “reasonable” rate that includes credits for taxes paid in other countries.

“I would still charge a tax on international earnings. I am a party of one on this topic,” he told Businessweek. “The issue is not that there’s a tax on international earnings. The issue is the existing tax has been crazy.”

Cook was also asked about Trump and his views of the president’s agenda. Cook said Trump’s focus on jobs was good, and that Apple would work with veterans to improve their access to health care, but pointed to big differences on immigration and climate.

Cook said he would have stayed in the Paris climate accord, which Trump promised to pull out of in a Rose Garden ceremony last month. However, Cook also seemed to disagree with the response by some CEO peers like Tesla Inc. TSLA, +5.04% Chief Executive Elon Musk, who said he would leave presidential councils after the move.

“At the end of the day, I’m not a person who’s going to walk away and say, ‘If you don’t do what I want, I leave.’ I’m not on a council, so I don’t have those kind of decisions,” Cook said. “But I care deeply about America. I want America to do well. America’s more important than bloody politics from my point of view.”
