– President-elect Joe Biden is warning of massive damage done to the national security apparatus by the Trump administration and “roadblocks” in communication between agency officials and his transition team that could undermine Americans’ security. “Right now we just aren’t getting all the information that we need from the outgoing administration in key national security areas.

Trump himself has had a contentious relationship with the intelligence community, criticizing its findings that Russia interfered in the 2016 election to boost his candidacy.

The U.S. Court of Appeals for the District of Columbia reversed a lower court’s dismissal of the House Democrats’ lawsuit. The appeals panel cited the House's argument that it was cut out of its “constitutionally indispensable legislative role” when Trump unilaterally moved about $8 billion to border wall construction. House Democrats sued three months after the end of the longest government shutdown in U.S. history, triggered by Trump's demand for border wall funding. Another appeals court ruled in June against the transfer of money from military construction projects. Building a border wall was one of Trump's signature campaign pledges four years ago, though he promised then that Mexico would pay for the wall.

BEIJING – China’s Defense Ministry on Sunday blasted a critical U.S. report on the country’s military ambitions, saying it is the U.S. instead that poses the biggest threat to the international order and world peace. “Rather than reflecting on itself, the U.S. issued a so-called report that made false comments about China’s normal defense and military construction," he said in the statement. “We call on the U.S. to view China’s national defense and military construction objectively and rationally, cease making false statements and related reports, and take concrete actions to safeguard the healthy development of bilateral military relations." Running to more than 150 pages, the Defense Department report examined the PLA's technical capabilities, doctrines and the ultimate aims of China's military buildup. China's military capabilities dwarf those of the island of 23 million in numerical terms, although any invasion of Taiwan would be complex and would carry major political risks, the report said.

WASHINGTON – The Defense Department is rescinding its order to shut down the military’s independent newspaper, Stars and Stripes, in the wake of a tweet late last week by President Donald Trump vowing to continue funding the paper. The House-passed version of the Pentagon's 2021 budget contains funding for the paper’s publication, but the Senate has not yet finalized a defense funding bill. The first newspaper called Stars and Stripes was very briefly produced in 1861 during the Civil War, but the paper began consistent publication during World War I. When the war was over, publication ended, only to restart in 1942 during World War II, providing wartime news written by troops specifically for troops in battle. Although the paper gets funding from the Defense Department, it is editorially independent and is delivered in print and digitally to troops all over the world.

WASHINGTON President Donald Trump said Monday that top Defense Department leaders want to keep waging wars in order to keep defense contractors happy.Trump continues to fight allegations that he made offensive comments about fallen U.S. service-members, including calling World War I dead at an American military cemetery in France losers and suckers in 2018. The Atlantic first reported on the anonymously sourced allegations. At a White House news conference Monday, Trump repeated his claim that the story was a hoax and said: Im not saying the militarys in love with me. Gen. Mark Milley, chairman of the Joint Chiefs of Staff, has also expressed regret for walking with Trump through Lafayette Square in what turned out to be a photo op during the protests.

WASHINGTON – President Donald Trump said Friday that he won't allow the Pentagon to cut funding for the military's independent newspaper, Stars and Stripes, effectively halting Defense leaders' plan to shut the paper down this month. “The United States of America will NOT be cutting funding to @starsandstripes magazine under my watch,” Trump tweeted. The Defense Department has ordered the paper to halt publication by Sept. 30, and dissolve the organization by the end of January. The Pentagon proposed cutting the paper's funding when making its budget request earlier this year, triggering angry reactions from members of Congress. The House-passed version of the Pentagon budget contains funding for the paper's publication, but the Senate has not yet finalized a defense funding bill.

Are they going to build family housing?Most troops in Germany are assigned there, and are not on short-term deployments.
