Almost four years after George W. Bush left office , neoconservatives still have n't grappled with his worst failures , as Jennifer Rubin reminds us in the clip above . 
Asked to name Bush 's biggest mistake , she offers two answers : -LRB- 1 -RRB- "His failure to forcefully and promptly reply about the scurrilous allegation that he lied about weapons of mass destruction in Iraq ;" and -LRB- 2 -RRB- his choice at the beginning of his second term to pursue private Social Security accounts before immigration reform . 
As I see it , the Bush Administration was constantly avowing that it did n't lie about pre-war intelligence , and immigration reform was unlikely to pass regardless of when it was attempted . 
But the larger problem with these answers is the notion that Bush 's political mistakes were more grave than the numerous substantive errors that he made while in the White House . 
My own list of Bush Administration mistakes is much longer , but even controlling for the dramatically different ideological perspective of neoconservatives , Rubin 's picks betray a profound failure to grapple with a presidency that needlessly weakened America in multiple ways .

“What is happening in Catalonia is real  whether they like it or not. Millions of people have voted  who want to decide. We have to talk about this ”  he  said.

Speculation has persisted that  Koike   a former LDP member and defense minister  would resign to run for a seat in parliament needed to make a bid for the premiership.
“I have been saying I will not run for the election from the beginning ”  Koike  said in an interview with the Yomiuri newspaper reported on Tuesday.
If  Koike  does not personally contest this election  then analysts believe she would hope her party positions itself to win the next national poll  and that she gains a voter boost from the 2020 Tokyo Olympics.
But  Koike ’s new Party of Hope - launched just last week as a “reformist  conservative” alternative to Abe’s equally conservative LDP - has clouded the outlook amid signs voters are disillusioned with Abe after nearly five years in power.
 Koike ’s dilemma was whether to run for a seat now and face a backlash from voters for quitting as governor little more than a year since she defied the LDP to run successfully for the post  or risk letting a shot at the top job slip through her fingers.
“ Koike  is tough   she ’s resilient and  she  can tap into the fact that Abe’s negative ratings are pretty high and a lot of people out there are unhappy with him ” Kingston said.
