He made the remarks at a hearing with members of the Senate Armed Services Committee yesterday, chaired by Senator John McCain who criticised the Trump regime for not coming up with a policy for Afghanistan despite being in office for six months.
"I think Taliban had a good last year and they're trying to have a good one this year, sir. I think we may be able to, by a change in some of our concepts of operations, help them with air support and fire support. That'll put the enemy on the back foot. Right now, I believe that the enemy is surging, right now," Mattis said.
McCain rued that despite all the sacrifices made by US soldiers, Afghanistan is still a nation at war.
"We're now six months into this administration, we still haven't got a strategy for Afghanistan. It makes it hard for us to support you when we don't have a strategy. We know what the strategy was for the last eight years, don't lose. That hasn't worked," he said.
"The sacrifice of these heroes is a painful reminder that America is still a nation at war. That is true in Afghanistan where, after 15 years of war, we face a stalemate and urgently need a change in strategy, and an increase in resources if we are to turn the situation around," he said.
Mattis assured him that that the current regime will son brief them about the policy on Afghanistan by mid-July.
"I believe by mid-July we will be out to brief you in detail. We are putting it together now and there are actions being taken to make certain that we don't pay a price for the delay. But we recognise the need for urgency and your criticism is fair," he said.
"We are not winning in Afghanistan right now. We will correct this as soon as possible. I believe the three things we are asking for stand on their own merit, however, as we look more broadly at the protection of the country. But that in no way does that relieve me of the need to deliver that strategy to you," he added.
The defence secretary also hoped that the violence in Afghanistan will be reduced significantly, especially in the populated centers.
"...The Afghan government has got a degree of integrity in what it is contributing to its people -- the government services. The corruption has been driven down. But, most of all, that the Taliban no longer has the freedom of movement that we're seeing right now that has been rolled back," he said.
Mattis also pitched for allying with Afghan forces to fight against the extremists.
"I think one of the ways that we get after that is by more effectively assisting them, both in planning operations and delivering combined arms, most specifically the aviation capabilities.
"So, continuing to grow their aviation capability and providing them support, while they grow their aviation capability, will be a key piece in mitigating casualties," he said.
Responding to another question, Mattis hoped that the Afghan government with international help will be able to handle the violence and drive it down to a level that local security forces can handle it.
Three US soldiers were killed and another wounded on Saturday when they were attacked by an Afghan soldiers, who was then killed.
Two US Army Rangers died in a April 27 raid on an IS compound in eastern Afghanistan. Officials were investigating whether they were killed by friendly fire in the opening minutes of the three-hour battle.
Their deaths came just days after a US Army special forces soldier was also killed in the region.
The Afghanistan war has been dragging on since October 2001, and the US-led coalition ended their combat mission against the Taliban in 2014 but they are increasingly involved in backing up Afghan forces on the battlefield.
